    Alexander Rehmer, Marco Klute, Andreas Kroll, Hans-Peter Heim A Digital Twin for Part QualityPrediction and Control in Plastic Injection Molding 2024 Modeling, Identification and Control for Cyber-Physical Systems Towards Industry 4.0, chapter: 4, pp. 79-109, Emerging Methodologies and Applications in Modelling, Identification and Control, Academic Press  DOI , URL  
    Abstract: The plastic injection molding process has been established as the most widespread manufacturing process in the plastic processing industry. It is employed by almost 70 % of all plastic processing companies. Among the decisive factors contributing to its prevalence are the ability to manufacture parts with intricate geometries and a high degree of automation. There are approaches of varying complexity to control the part quality to reduce waste and increase the efficiency of the process: The industry standard is the control of the so-called machine-variables i.e. the process variables that are measured on the machine side of the process. This does not take into account any variables that reflect the true state of the emerging part. For this reason the scientific community aims to control process variables that are measured cavity-side, more precisely the pressure in the mold cavity. However the implementation of pressure control requires significant control knowledge and is not suitable for large-scale industrial application. The objective of this contribution is therefore to transform an ordinary machine-variable controlled injection molding machine to a Cyber Physical Production System (CPPS) via augmentation by a digital twin (DT). The DT will predict the part quality from process variables. To this end a state-of-the-art industrial injection molding machine was equipped with additional sensors that measure in-cavity process variables. Moreover an in-line quality measuring cell was added. By doing so all machine, processes and quality data required for data-driven modeling and perspectively control are acquired. Subsequently an internal dynamics approach for predicting final batch quality from process value trajectories is proposed and compared to the current state-of-the-art modeling approaches in a case study.

    Miguel Mendez, Jannik Ebert, Lars Sommerlade, Robert Schmoll, Andreas Kroll Comparative Assessment of the Size-of-Source Effect in Middle and Long-Wavelength Infrared Cameras 2023 QIRT Asia 2023 - The 4th Quantitative Infrared Thermography Conference, Abu Dhabi, U.A.E., Oct. 30 - Nov. 3   
    Abstract: Current radiometric calibration procedures for thermal imaging cameras are usually performed for a single calibration geometry. The uncertainty estimated from such procedure only represents the calibration scenario and does not account for variation of the emitting source's size; this is known as the size-of-source effect (SSE). In this work, the measurements of the SSE for four thermal imaging cameras (two in the long-wavelength and two in the middle-wavelength infrared range) are presented. The investigation shows that the SSE is smaller for the middle-wavelength cameras.

    Abstract: Recurrent Neural Networks are applied in areas such as speech recognition, natural language and video processing, and the identification of nonlinear state space models. Conventional Recurrent Neural Networks, e.g. the Elman Network, are hard to train. A more recently developed class of recurrent neural networks, so-called Gated Units, outperform their counterparts on virtually every task. This paper aims to provide additional insights into the differences between RNNs and Gated Units in order to explain the superior perfomance of gated recurrent units. It is argued, that Gated Units are easier to optimize not because they solve the vanishing gradient problem, but because they circumvent the emergence of large local gradients.

    Sören Dierks, Andreas Kroll Remote quantification of methane leaks in the laboratory and in biogas plants 2021 International Journal of Remote Sensing, vol. 42, no. 20, pp. 7978–-8003  DOI  
    Abstract: Gas leaks can occur not only in industrial environments such as refineries but also in biogas plants. The main compound of the emitted biogas is methane, which is a greenhouse gas with a higher global warming potential than carbon dioxide (CO 2 ). Considering that the climate change and the reduction of greenhouse gases are becoming more and more important, it is crucial to be able to not only localize but also to quantify methane leakages. Based on the quantification of methane leakages, not only the effect of the effluent gases to the atmosphere but also the economic loss can be estimated. Another aspect is safety: biogas consists of different gases, mainly methane which can create an explosive mixture with air, but also hydrogen sulphide, which is toxic. This motivates remotely measuring the gas emissions. In this paper a remote measurement system and model is presented to estimate the methane volume flow due to a leak based on infrared optical sensors and sensor data fusion. The sensors are calibrated and the system is tested in the laboratory as well as in biogas plants. The laboratory results show that the measurement model allows an estimation of the methane volume flow if the assumptions of the measurement model are met. The highest relative deviations occur for small reference methane volume flows while the absolute deviations are similar. In contrast to the laboratory measurements the results of the measurements in biogas plants show partially high deviations from the reference. These deviations can have multiple reasons which cannot be determined for each single case because many of them occur at the same time. Future work includes improvements in order to reduce the deviations of the methane volume flow estimation. This could be done not only by improving the processing steps of the velocity estimation but also by using more accurate sensors

    Abstract: In recent years, due to the availability of affordable 3D sensors and the increased computing power, various methods for the generation of 3D thermograms have been developed. 3D thermal imaging describes the fusion of geometry and temperature data. A well-established approach is the fusion of data from depth and long-wave infrared (LWIR) cameras. However, these models generated in real-time have the limitation that the model size is limited due to inefficient data storage approach. Newer algorithms from Computer Vision promise to overcome this limitation by more efficient data handling and storage. Within this work, three state of the art 3D reconstruction algorithms from the computer vision community are compared and one of these is extended by overlaying thermal data, which allows the creation of large-scale 3D thermograms with a portable 3D measurement system. For this purpose, a geometric calibration is required, the data structure is adapted, and the handling of cyclic non-uniformity corrections required for uncooled LWIR cameras is described. The results will show exemplary 3D thermograms and the advantages compared to current existing systems.

    Abstract: This paper is concerned with the analysis of optimization procedures for optimal experiment design for locally affine Takagi-Sugeno (TS) fuzzy models based on the Fisher Information Matrix (FIM). The FIM is used to estimate the covariance matrix of a parameter estimate. It depends on the model parameters as well as the regression variables. Due to the dependency on the model parameters good initial models are required. Since the FIM is a matrix, a scalar measure of the FIM is optimized. Different measures and optimization goals are investigated in three case studies.

    Abstract: In data-driven modeling besides the point estimate of the model parameters, an estimation of the parameter uncertainty is of great interest. For this, bounded error parameter estimation methods can be used. These are particularly interesting for problems where the stochastical properties of the random effects are unknown and cannot be determined. In this paper, different methods for obtaining a feasible parameter set are evaluated for the use with Takagi-Sugeno models. Case studies with simulated data and with measured data from a manufacturing process are presented.

    Abstract: Ist Wissen über die stochastischen Eigenschaften eines dynamischen Prozesses verfügbar, so kann dies zur Verbesserung der Modellparameterschätzung erücksichtigt werden. Dabei trifft die oft gemachte Annahme i.i.d. normalverteilter Zufallsgrößen bei technischen Systemen häufig nicht zu. Im Beitrag werden deshalb die Dichtefunktionen der Zufallsgrößen als Gaußsche Mischmodelle mittels eines Multistart-Expectation-Maximization-Algorithmus geschätzt. Da die Residualdichtefunktionen zu Beginn der Identifikation nicht verfügbar sind, werden diese aus der Streuung von Wiederholexperimenten approximativ ermittelt und zur Maximum-Likelihood-Schätzung von Takagi-Sugeno-Modellen genutzt. Wegen der ausgeprägten Multimodalität der resultierenden Likelihood-Funktion wird dazu Partikelschwarm-Optimierung eingesetzt. Die Vorgehensweise wird an einem industriellen servo-pneumatischen Linearantrieb demonstriert.

    Abstract: In this paper, the problem of order selection for nonlinear dynamical Takagi-Sugeno (TS) fuzzy models is adressed. It is solved by reformulating the TS model in its Linear Parameter Varying (LPV) form and applying an extension of a recently proposed Regularized Least Squares Support Vector Machine (R-LSSVM) technique for LPV models. For that, a nonparametric formulation of the TS identi cation problem is proposed which uses data-dependent basis functions. By doing so, the partition of unity of the TS model is preserved and the scheduling dependencies of the model are obtained in a nonparametric manner. For the local order selection, a regularization approach is used which forces the coeffcient functions of insignifcant values of the lagged input and output towards zero.

    Abstract: In this contribution the optimal experiment design for the identification of linear affine Takagi-Sugeno (TS) models is discussed. The parameters of these models can be separated into local model and partition parameters which also allows for a separation of the design. The presented optimal design is based on the Fisher Information Matrix (FIM) and its objective is to minimize the parameter estimation uncertainty. In this contribution parameters of a standard test signal type (multi-step) are optimized to achieve this objective. The effectivity of FIM-based designs for nonlinear models depends on initial identification including structural decisions. The general functionality of the presented method is demonstrated on a case study.

    Abstract: In this article, two data-driven modeling approaches are investigated, which allow an explicit modeling of uncertainty. For this purpose, parametric Takagi-Sugeno multi-models with bounded-error parameter estimation and nonparametric Gaussian process regression are applied and compared. These models can for instance be used for robust model-based control design. As an application, the prediction of residual stresses during hard turning depending on the machining parameters and the initial hardness is considered.

    Abstract: Recurrent Neural Networks are applied in areas such as speech recognition, natural language and video processing, and the identification of nonlinear state space models. Conventional Recurrent Neural Networks, e.g. the Elman Network, are hard to train. A more recently developed class of recurrent neural networks, so-called Gated Units, outperform their counterparts on virtually every task. This paper aims to provide additional insights into the differences between RNNs and Gated Units in order to explain the superior perfomance of gated recurrent units. It is argued, that Gated Units are easier to optimize not because they solve the vanishing gradient problem, but because they circumvent the emergence of large local gradients.

    Abstract: Experiments to collect data for system identification in industrial plants are constrained due to production and safety requirements. In such situations, logged historical data can be used for system identification instead. However, these recorded data are predominantly stationary in continuously operated plants since processes are seldom excited during normal operation. Performing system identification with such data will yield numerical problems. Alternately, the "most" informative sequences can be extracted and used for system identification. Current data selection methods have several drawbacks. They are constrained to Single-Input Single-Output (SISO) modeling problems. The methods are not robust against correlated noise which is a disadvantage when using real data sets. Moreover, setting design parameters requires some information about the process that is not always available. In this contribution, an alternative data selection method for system identification is presented and evaluated in a case study. In contrast to current approaches, the proposed method does not require data normalization to detect transient changes. It can be used in Multi-Input Single-Output (MISO) systems operating in open or closed loop. An instrumental variables (IV) method is used in the algorithm which provides robustness against non-white noise. Results from a simulation case study of a multivariable system show that models with similar accuracy are obtained when using the intervals retrieved by the data selection method as when using the entire data set.

    Abstract: This paper is concerned with the test signal design for the identification of the partition parameters of locally affine Takagi-Sugeno-(TS-)Models. The basic idea is that data should be generated in local model transition areas in the scheduling space. A reference system output that represents the desired path in the scheduling space is forced upon the underlying system through a combination of a feed-forward and feedback control scheme. The system is then identified in an iterative closed-loop identification procedure. This method has been applied to an artificial system to demonstrate its potential.

    Matthias Gringard, Andreas Kroll Optimal Experiment Design for Identifying Dynamical Takagi-Sugeno Models with Minimal Parameter Uncertainty 2018 18th IFAC Symposium on System Identification, Stockholm, Sweden, IFAC, 09-11. July  URL  
    Abstract: In this contribution the optimal experiment design for the identification of linear affine Takagi-Sugeno (TS) models is discussed. The parameters of these models can be separated into local model and partition parameters which also allows for a separation of the design. The presented optimal design is based on the Fisher Information Matrix (FIM) and its objective is to minimize the parameter estimation uncertainty. In this contribution parameters of a standard test signal type (multi-step) are optimized to achieve this objective. The effectivity of FIM-based designs for nonlinear models depends on initial identification including structural decisions. The general functionality of the presented method is demonstrated on a case study.

    Abstract: Konventionelle Fahrerlose Transportsysteme (FTS) sind seit Jahrzehnten eine gängige Lösung für Intralogistikaufgaben [1]. Die Navigation orientiert sich oft an optischen, induktiven oder magnetischen "Spuren", die Änderungen der Routen aufwendig und kostspielig machen. Ein wichtiges Merkmal ist ein übergeordneter Sicherheitskreis, der diese anhält, falls beispielsweise ein (Laserscanner/Kontaktschalter-basiertes) Kollisionsschutz-System eingreift. Zudem werden die Spuren meist nur in eine Richtung benutzt und die Behandlung von auf der Strecke abgestellten Hindernissen erfolgt passiv und die Fahrgeschwindigkeit ist in Umgebungen mit vielen Menschen langsam. In Zukunft sollen FTS ähnlich autonomer Fahrzeuge im öffentlichen Straßenverkehr den gesamten freien Bereich zur Navigation nutzen, nicht an feste Spuren gebunden sein, Engstellen mit Gegenverkehr meistern, Hindernisse effizient umfahren, sich bei der Routenplanung mit anderen autonomen Systemen und anzufahrenden Stationen abstimmen und die Bewegung "chaotischer Verkehrsteilnehmer" abschätzen und berücksichtigen.

    Abstract: The formation of foam in amine units is an issue that plant operators and field personnel are confronted with on a regular basis. The inability to take proper actions in due time may result in plant downtime and increased emissions. Steep rises in differential pressure indicate foam formation, and are monitored manually in practice. Antifoaming agent is added in order to reduce foaming, but this is usually carried out under time pressure. Hence, plant operating authorities have expressed a strong interest in a data-driven solution capable of providing an early warning against foaming. The classical univariate alarm associated with differential pressure can be ineffective for foaming detection due to high misdetection rates and its lateness of detection. Modern univariate approaches based on pattern recognition techniques may not be suitable either for an early detection, as no universally distinctive features of differential pressure are observed prior to foaming in the present study. In this contribution, the multivariate statistical process monitoring approach based on principal component analysis (PCA) is applied to the early detection of foaming in a continuously operated Shell Claus Off-gas Treating (SCOT) unit of a major refinery in Germany. The results are extended to facilitate fully automated and adaptive modeling based on exponentially weighted recursive principal component analysis (EWRPCA).

    Salman Zaidi, Andreas Kroll NOE TS Fuzzy Modelling of Nonlinear Dynamic Systems with Uncertainties using Symbolic Interval-valued data 2017 Applied Soft Computing, vol. 57, pp. 353-362  DOI , URL  
    Abstract: An approach to Nonlinear Output Error (NOE) modelling using Takagi - Sugeno (TS) fuzzy model for a class of nonlinear dynamic systems having variability in their outputs is presented. Furthermore, the approach is compared and graphically illustrated with other alternate approaches on the basis of interval data and interval membership functions. Assuming the identification method can be repeated offline a number of times under similar conditions, multiple input - output time series can be obtained from the underlying system. These time series are pre-processed using the techniques of statistics and probability theory to generate the envelopes of response (curves outlining the upper and lower extremes of response) at each time instant. Two types of envelopes are described in this research: the max - min envelopes and the envelopes based on the confidence intervals provided by extended Chebyshev's inequality. By incorporating interval data in fuzzy modelling and using the theory of symbolic interval-valued data, a TS fuzzy model with interval antecedent and consequent parameters is obtained. This algorithm provides a model for predicting the expected response as well as envelopes. In order to validate the presented model, a simulation case study is devised in this paper. Moreover, it is demonstrated on the real data obtained from an electro-mechanical throttle valve.

    Abstract: Infrared thermography is a widely used technique to measure and portray the surface temperature of an object in form of thermal images. Two dimensional images, however, have some inherent limitations with regard to the fidelity with which they can depict the surface temperature of a three dimensional object. In the past two decades, there have been several works describing different techniques to generate 3D models textured with thermal information using various combinations of sensors in order to address some of these limitations. Most of these approaches generate 3D thermograms of an object from a single perspective with bulky measurement systems and therefore do not address problems that arise when scanning objects in a continuous manner from multiple perspectives. But reductions in cost, size and weight of infrared and depth-sensing cameras as well as a significant increase in computational power of personal computers have enabled the development of low cost, handheld, real-time 3D thermal imaging systems. This article elaborates through a series of experiments on the main factors that affect the real-time generation of high fidelity 3D thermograms with such a system and demonstrates how taking this factors into consideration significantly improves the appearance and fidelity of the generated 3D thermogram. Most of the insight gained in this article can be transferred to 3D thermal imaging systems based on other combination of sensors.

    Abstract: Gegenstand der Erfindung ist ein Verfahren zum Erzeugen eines dreidimensionalen Thermogramms eines Objekts (2), bei dem geometrische Daten des Objekts (2) erfasst werden und anhand dieser ein dreidimensionales Modell des Objekts (2) erzeugt wird. Zusätzlich werden für Objektpunkte (9) von zumindest einer Teiloberfläche (10) des Objekts (2) Temperaturmesswerte erfasst, wobei für jeden Objektpunkt (9) neben dem Temperaturmesswert zusätzlich Daten zu Aufnahmebedingungen erfasst werden. Die erfassten Temperaturmesswerte werden zugehörigen Objektpunkten einer Teiloberfläche des dreidimensionalen Modells des Objekts (2) zugeordnet, so dass ein dreidimensionales Thermogramm für die Teiloberfläche (10) des Objekts (2) erzeugt wird. Erfindungsgemäß wird das so erzeugte dreidimensionale Thermogramm auf die zugehörige Teiloberfläche (10) des Objekts (2) projiziert. Nachfolgend werden erneut Temperaturmesswerte und von Daten zu den Aufnahmebedingungen für Objektpunkte einer oder der Teiloberfläche (10) des Objekts (2) erfasst. Für Objektpunkte (9), für die bereits ein Temperaturmesswert und Daten zu den Aufnahmebedingungen erfasst wurden, werden die Daten zu den Aufnahmebedingungen verglichen, wobei dem Objektpunkt in dem erzeugten dreidimensionalen Thermogramm automatisch der neu erfasste Tempertaturmesswert zugeordnet wird, wenn der neu erfasste Temperaturmesswert unter besseren Aufnahmebedingungen erfasst wurde.

    Andreas Kroll, Axel Dürrbaum On optimal experiment design for identifying premise and conclusion parameters of Takagi-Sugeno models: nonlinear regression case 2017 Applied Soft Computing, vol. 60, pp. 407 - 422  DOI , URL  
    Abstract: Optimal Experiment Design (OED) is a well-developed concept for regression problems that are linear-in-the-parameters. In case of experiment design to identify nonlinear Takagi-Sugeno (TS) models, non-model-based approaches or OED restricted to the local model parameters (assuming the partitioning to be given) have been proposed. In this article, a Fisher Information Matrix (FIM) based OED method is proposed that considers local model and partition parameters. Due to the nonlinear model, the FIM depends on the model parameters that are subject of the subsequent identification. To resolve this paradoxical situation, at first a model-free space filling design (such as Latin Hypercube Sampling) is carried out. The collected data permits making design decisions such as determining the number of local models and identifying the parameters of an initial TS model. This initial TS model permits a FIM-based OED, such that data is collected which is optimal for a TS model. The estimates of this first stage will in general not be ideal. To become robust against parameter mismatch, a sequential optimal design is applied. In this work the focus is on D-optimal designs. The proposed method is demonstrated for three nonlinear regression problems: an industrial axial compressor and two test functions.

    Abstract: Die Modellfabrik µPlant stellt eine modulare, stofflich und informationstechnisch vernetzte Miniaturfabrik dar. Sie besteht aus mehreren unterschiedlichen Modulen, in denen kontinuierliche Prozesse oder Stückgutprozesse ablaufen, einem Lager mit Knickarmroboter sowie mehreren mobilen Robotern für einen flexibel einstellbaren Materialfluss zwischen den einzelnen Modulen. Die Module haben jeweils eigene, für den jeweiligen Modultyp spezifisch ausgewählte Automatisierungssysteme. Die Modellfabrik dient im Bereich der Lehre der Qualifizierung Studierender an modernen und an zukünftigen Automatisierungstechnologien. In der Forschung dient sie als Testeinrichtung für Methoden aus den Bereichen Überwachung, Modellbildung, Regelung und Optimierung. In einem Vortrag wird eine technische Übersicht über die Anlage gegeben und ihre Funktion erläutert. Anschlißend findet eine Vorführung der Modellfabrik statt. Univ.-Prof. Dr.-Ing. Andreas Kroll leitet das Fachgebiet Mess- und Regelungstechnik im Fachbereich Maschinenbau an der Universität Kassel. Zudem ist er Arbeitskreisleiter des AK 4 "Mess- und Regelungstechnik" im VDI Bezirksverein Nordhessen.

    Alexander Schrodt, Andreas Kroll On Iterative Closed-Loop Identification Using Affine Takagi-Sugeno Models and Controllers 2017 International Journal of Fuzzy Systems, vol. 19, no. 6, pp. 1978-1988  DOI , URL  
    Abstract: Often models are used for controller design that was identified under the objective to well approximate the system under study. In this paper, a scheme for identifying discrete-time locally affine Takagi - Sugeno (TS) models is presented, which better reflects the dedicated model use for designing a TS controller. For this purpose, after an initial open-loop experiment and controller design step, additional experiments are carried out in closed loop, each followed by an identification and controller design step. The deployed TS controllers are of parallel distributed compensator type but augmented by parallel drift and steady-state error compensation. The focus in this work is on a complete method that is simple and usable for real-world applications. To illustrate the practicality of the method, it is demonstrated on a laboratory-scale three-tank system.

    Alexander Rehmer, Andreas Kroll An extension to RPCA parameter selection and process monitoring 2017 Proceedings of the 20th IFAC World Congress, pp. 15329-15334, IFAC   
    Abstract: Multivariate Statistical Process Control (MSPC) techniques such as Principal Component Analysis (PCA) and Partial Least Squares (PLS) have found wide application especially in the statistical modeling and monitoring of chemical processes. However, real industrial processes often violate the assumptions underlying MSPC since they exhibit timevarying and non-stationary behavior. Adaptive PCA-based monitoring procedures such as Moving Window PCA (MWPCA) and Recursive PCA (RPCA) have been proposed to tackle this issue. Although the parameter selection for those procedures is critical to their proper implementation, this topic is rarely covered in the literature. This paper examines two methods for MWPCA and RPCA parameter selection using the Tennessee Eastman process as an example. Based on the findings a novel procedure for RPCA parameter selection as well as a extension to RPCA will be proposed and demonstrated.

September  URL  
    Abstract: Compressed air is a widespread but costly energy carrier. Leaks account for 10 compressed air consumption in production facilities and their removal offers high potential for cost reduction. The turbulent flow from a leak causes broadband acoustic emissions. These are exploited for leak detection using a narrowband ultrasonic microphone that is insensitive to audible noise. A parabolic mirror or an acoustic horn is utilized to enhance the directivity and the received signal power of the microphone. The microphone is mounted on mobile service robots. In the project "Robotair" an automated guided vehicle (AGV) and a remotely controlled micro aerial vehicle (MAV) were used for robotized inspection of production facilities. In order to detect leaks, predefined areas are scanned. A leak is detected and localized based on the sensed peak amplitude of the ultrasound signal. The corresponding pose of the sensor facing the leak is determined based on the selflocalization of the robot. Leak localization is carried out by triangulation of two sensor poses. Tests were conducted in an automobile production facility to evaluate the performance of the system. A leak was placed in an assembly line and multiple measurements were taken from two positions with the AGV and the MAV. The leaks were successfully detected and localized.

    Chun Liu, Andreas Kroll Performance impact of mutation operators of a subpopulation-based genetic algorithm for multi-robot task allocation problems 2016 SpringerPlus Engineering, vol. 15, no. 1, August  DOI , URL  
    Abstract: Multi-robot task allocation determines the task sequence and distribution for a group of robots in multi-robot systems, which is one of constrained combinatorial optimization problems and more complex in case of cooperative tasks because they introduce additional spatial and temporal constraints. To solve multi-robot task allocation problems with cooperative tasks efficiently, a subpopulation-based genetic algorithm, a crossover-free genetic algorithm employing mutation operators and elitism selection in each subpopulation, is developed in this paper. Moreover, the impact of mutation operators (swap, insertion, inversion, displacement, and their various combinations) is analyzed when solving several industrial plant inspection problems. The experimental results show that: (1) the proposed genetic algorithm can obtain better solutions than the tested binary tournament genetic algorithm with partially mapped crossover; (2) inversion mutation performs better than other tested mutation operators when solving problems without cooperative tasks, and the swap-inversion combination performs better than other tested mutation operators/combinations when solving problems with cooperative tasks. As it is difficult to produce all desired effects with a single mutation operator, using multiple mutation operators (including both inversion and swap) is suggested when solving similar combinatorial optimization problems.

    Abstract: Optimal experiment design (OED) is a well-developed concept for linear regression and linear dynamical modeling problems. In case of nonlinear models, the dilemma is that in order to evaluate the Fisher Information Matrix (FIM) for experiment design, the parameters to be estimated are required to evaluate the FIM. In case of locally affine Takagi-Sugeno (TS) models and D-optimal designs, even a "robust" sequential OED may not be sufficiently robust against wrong assumptions on partition parameters. As remedy, a two stage experiment design is proposed: It uses a space-filling design to estimate good initial TS model parameters. These are used to initialize a robust sequential FIM-based OED. The method is demonstrated for a nonlinear regression problem.

    Abstract: Das erste deutschsprachige Lehrbuch zum Thema Computational Intelligence für Ingenieure - praxisbezogen, gut verständlich, inhaltlich auf dem neuesten Stand. Mit Online-Zusatzmaterial. Produktinfo: Beschreibung, Analyse und Entwurf technischer Systeme werden zunehmend komplexer und erfordern neuartige Lösungsansätze. Durch die Natur inspiriert entstanden verschiedene Berechnungsverfahren, die im Wissenschaftsgebiet der Computational Intelligence (CI) zusammengefasst sind. Hierzu zählen die etablierten Kernbereiche der Fuzzy-Systeme, Künstliche Neuronale Netze und Evolutionäre Algorithmen sowie aus diesen zusammengeführte Hybride Methoden. Hinzu kommen die noch jungen Gebiete der Schwarmintelligenz und der künstlichen Immunsysteme. So bewegt sich die CI an der Schnittstelle zwischen Ingenieurswissenschaften und Informatik. Dieses Buch bietet eine gut verständliche, vereinheitlichende und anwendungsorientierte Einführung in das Thema und vermittelt Studenten und berufstätigen Ingenieuren das notwendige Fachwissen. Neben den methodischen Erläuterungen sind einfach nachvollziehbare Beispiele integriert, die die Funktion der Methoden veranschaulichen. Darüber hinaus wurden Praxisbeispiele zur Illustration der praktischen Relevanz aufgenommen. Die Musterlösungen für Dozenten können auf der geschützten Webseite https://mrt-pc1.mrt.maschinenbau.uni-kassel.de/MRT/Bibliothek/Compagnon/ heruntergeladen werden.

Mit Online-Zusatzmaterial. Produktinfo: Beschreibung, Analyse und Entwurf technischer Systeme werden zunehmend komplexer und erfordern neuartige Lösungsansätze. Durch die Natur inspiriert entstanden verschiedene Berechnungsverfahren, die im Wissenschaftsgebiet der Computational Intelligence (CI) zusammengefasst sind. Hierzu zählen die etablierten Kernbereiche der Fuzzy-Systeme, Künstliche Neuronale Netze und Evolutionäre Algorithmen sowie aus diesen zusammengeführte Hybride Methoden. Hinzu kommen die noch jungen Gebiete der Schwarmintelligenz und der künstlichen Immunsysteme. So bewegt sich die CI an der Schnittstelle zwischen Ingenieurswissenschaften und Informatik. Dieses Buch bietet eine gut verständliche, vereinheitlichende und anwendungsorientierte Einführung in das Thema und vermittelt Studenten und berufstätigen Ingenieuren das notwendige Fachwissen. Neben den methodischen Erläuterungen sind einfach nachvollziehbare Beispiele integriert, die die Funktion der Methoden veranschaulichen. Darüber hinaus wurden Praxisbeispiele zur Illustration der praktischen Relevanz aufgenommen. Die Musterlösungen für Dozenten können auf der geschützten Webseite https://mrt-pc1.mrt.maschinenbau.uni-kassel.de/MRT/Bibliothek/Compagnon/ heruntergeladen werden.},

    Salman Zaidi, Andreas Kroll A Novel Approach to TS Fuzzy Modeling of Nonlinear Dynamic Systems with Uncertainties using Symbolic Interval-Valued Outputs 2015 Proceedings of the 17th IFAC Symposium on System Identification (SysID), pp. 1196 - 1201, Beijing, China, October 19-21  DOI  
    Abstract: A novel approach to Takagi-Sugeno (T-S) fuzzy modeling of a class of nonlinear dynamic systems having variability in their outputs for the Nonlinear Output Error (NOE) case is addressed in this article. Multiple input-output datasets were obtained by repeating the identification experiment. The variability in the output time series is captured by defining the envelops of response at each time instant. These envelops actually provide the confidence interval based upper and lower bounds of the output time series using the extended Chebyshev's Inequality. Different from the previous approach, in which two independent T-S fuzzy models were used for identifying each bound, a single T-S fuzzy model is identified in this work, which resulted in interval parameters for the antecedent and consequent variables. This is accomplished by first transforming the bounds into the symbolic interval-valued data and then using this data for identification. In order to get the expected response, the estimated lower and upper bound time series of the identified T-S fuzzy model were averaged out at each time instant, as permitted by the structure of the extended Chebyshev's Inequality. The proposed approach is demonstrated and validated for the experimental data obtained from diesel-engine electro-mechanical throttle valve.

    Abstract: In infrared thermography, the temperature measured by a thermal imaging device varies with the position and orientation of the camera with respect to an object's surface. 3D thermography has hence the potential to depict the surface temperature of objects with higher fidelity than conventional 2D thermography. So far the problem of assigning temperature values that correspond to the same surface but were obtained from different perspectives has been addressed by simply overwriting previous values with new values or by averaging the measured values according to a weighted averaging scheme. A new approach to map temperature values onto a 3D model is proposed that results in a more faithful representation of an object's real surface temperature in form of a 3D thermogram. Temperature values are assigned in real time to the 3D model taking into consideration the observation conditions under which they were measured. These conditions are also made available to the user in form of textured 3D models, where the texture color depicts the level of confidence associated to the thermal measurements. These textures provide useful additional information about the 3D thermogram. The new approach is especially helpful in the real-time generation of 3D thermograms as the user gets live feedback on the quality of the thermal model being generated.

    Andreas Kroll, Axel Dürrbaum On joint optimal experiment design for identifying partition and local model parameters of Takagi-Sugeno models 2015 Proceedings of the 17th IFAC Symposium on System Identification (SysID), pp. 1427 - 1432, Beijing, China, October 19-21  DOI  
    Abstract: Optimal Experiment Design (OED) is a well-developed concept for regression problems that are linear-in-their-parameters or for linear dynamical models. In case of nonlinear Takagi-Sugeno models either non-model-based experiment design or OED restricted to the local model parameters has been examined. This article proposes a joint design of local model and partition parameters that bases on the Fisher Information Matrix (FIM). For this purpose, a symbolic description of the joint FIM is derived. Its heterogeneous structure can make it badly conditioned, complicating computation of the determinant for D-optimal design. This problem is relaxed using determinant decomposition. A theoretical analysis and a case study show that experiment design for local model and partition parameters may significantly differ from each other.

    Salman Zaidi, Andreas Kroll On Identifying Envelop Type Nonlinear Output Error Takagi-Sugeno Fuzzy Models for Dynamic Systems with Uncertainties 2014 19th IFAC World Congress, pp. 3226-3231, Cape Town, South Africa, 24-29. August  DOI  
    Abstract: In modeling of a stochastic nonlinear dynamic system from input-output data, it may be of interest to model uncertainty in the underlying system besides predicting a most likely or average response of the system. Due to stochasticity in the system behavior, the data obtained for identification can be considered as one realization of the underlying stochastic phenomenon. In order to effectively deal with the identification of such systems, it may be advantageous to repeat the identification experiment multiple times under similar conditions. The multiple input-output time series generated in this way thus contain information about stochastic variations within the system. This paper presents one of the possible approaches to effectively deal with identification in such scenario in the framework of Nonlinear Output Error (NOE) Takagi-Sugeno (TS) fuzzy models. Based on extended Chebyshev's inequality for finite samples, the lower and upper boundaries of the output time-series are obtained using (1-$\alpha$) confidence interval (envelops of the response). The proposed identification algorithm provides a model for predicting the most likely value as well as the boundary models for predicting the envelops of the output signal. The experimental results for an electro-mechanical throttle shows the applicability and validity of the proposed approach.

    Moritz Wagner, Andreas Kroll A method to identify hybrid systems with mixed piecewise affine or nonlinear models of Takagi-Sugeno type 2014 13th European Control Conference (ECC 14), pp. 394 - 399, Strasbourg, IEEE, 25-27. June 2014  URL  
    Abstract: A clustering-based method to identify models that are piecewise affine or of Takagi-Sugeno type is presented. As prototype-based clustering algorithms, which are well suited for partitioning, frequently converge to unwanted local solutions, density-based noise clustering is used to initialize them. The clustering acts in a mixed parameter-position feature space and divides the data into separate sets for identifying local models and partition boundaries, which are assumed to be piecewise planar. The obtained partitions are tested on linearity and otherwise replaced each by a TS model that is identified from the respective data. The method is demonstrated for a test problem that includes switching, local polynomial nonlinearity as well as non-convex partition boundaries.

    Abstract: Using benchmark problems to demonstrate and compare novel methods to the work of others could be more widely adopted by the Soft Computing community. This article contains a collection of several benchmark problems in nonlinear control and system identification, which are presented in a standardized format. Each problem is augmented by examples where it has been adopted for comparison. The selected examples range from component to plant level problems and originate mainly from the areas of mechatronics/drives and process systems. The authors hope that this overview contributes to a better adoption of benchmarking in method development test and demonstration.

    Abstract: Nine project partners developed the prototype of an autonomous mobile robot for detecting gas leaks in extensive industrial plants within the context of the ÄUTONOMIK" programme of the German Federal Ministry for Economic Affairs and Energy. The system's autonomous mobility was put into practice using various sensors for auto-localisation and navigation. In addition, it includes an option to intervene manually in the process using teleoperation. Equipped with video and remote gas detection technology, the robot can carry out inspections in industrial plants without having to enter possible hazard areas and without any person present on site. The robot can be used for routine inspection of plants or systematic examination of specific parts of the plant. Using remote metrology technology, it is also possible to inspect parts of the plant that are difficult to inspect using traditional measuring instruments due to limited accessibility.

    Abstract: Optical IR cameras for gas visualization/imaging have gained acceptance and popularity in the past years. With these devices the scene is displayed as a thermal image while the gas is visible as hot/cold haze. As this is an imaging technique the operator can easily inspect large areas and detect and pinpoint leaks. The interpretation and analysis of the data is however still being carried out manually with little assistance from the camera. This article briefly presents the measurement method, discusses identifiable characteristics of gas clouds and the necessary steps for automating the image processing of the recorded measurement sequences.

    Abstract: Early detection of gas leakages in petrochemical plants is of great concern due to their potential threat to human safety, the environment and the infrastructure. Hand-held devices based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology have proven to be an effective way to detect and locate such leaks. The theory behind these devices is well documented, but little information is available on the effects that laser beam divergence has on the ability to detect gas plumes at long distances. This contribution attempts to explain how the background reflectance and the laser intensity profile affect the concentration readings as the distance to the objects under inspection increases.

The theory behind these devices is well documented, but little information is available on the effects that laser beam divergence has on the ability to detect gas plumes at long distances. This contribution attempts to explain how the background reflectance and the laser intensity profile affect the concentration readings as the distance to the objects under inspection increases.},

    Abstract: Uncontrolled emissions of harmful gases pose a real threat to human safety and the environment. A cost effective way to effectively monitor the presence of such gases in large environments like industrial plants is highly desirable. This paper discusses the issues that arise when using retro-reflectors to extend the operating range of a commercial device that utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS) for remote gas sensing.

    Abstract: Im Rahmen des Förderprogramms AUTONOMIK des Bundesministeriums für Wirtschaft und Technologie wurde in einem Konsortium aus neun Projektpartnern der Prototyp eines autonomen mobilen Roboters zur Gaslecksuche in ausgedehnten Industrieanlagen entwickelt. Anhand verschiedener Sensorik zur Selbstlokalisierung und Navigation wurde die autonome Beweglichkeit des Systems für beliebige Anlagen realisiert, mit der Option anhand von Teleoperation manuell in den Prozess einzugreifen. Ausgestattet mit Video- und Gasfernmesstechnik ist der Roboter imstande, Inspektionsaufgaben in Industrieanlagen durchzuführen, ohne in mögliche Gefahrenbereiche direkt einfahren zu müssen und ohne, dass ein Mensch vor Ort anwesend ist. Der Roboter kann zur routinemäßigen Inspektion von Anlagen oder zur gezielten Untersuchung spezifischer Anlagenteile engesetzt werden. Dank der verwendeten Fernmesstechnik können auch Anlagenteile inspiziert werden, die aufgrund ihrer beschränkten Zugänglichkeit mittels herkömmlicher Messtechnik nur schwer zu inspizieren sind.

    Gero Bonow, Andreas Kroll Gas leak localization in industrial environments using a TDLAS-based remote gas sensor and autonomous mobile robot with the Tri-Max method 2013 IEEE International Conference on Robotics and Automation (ICRA), pp. 987 - 992, IEE, Karlsruhe, Germany, May  DOI  
    Abstract: In order to automate routine inspections in large industrial environments, a mobile robotic system is being developed in the RoboGasInspector project. The robot's sensor-head consists of different instruments for remote gas sensing using multiple measurement principles. This contribution focuses on Tunable Diode Laser Absorption Spectroscopy (TDLAS). The measurement device allows quantitative gas concentration measurements and achieves high sensitivity due to the active measurement principle. On the contrary, TDLAS systems measure the concentration along a path at a time and require a diffusely reflecting background. Using a pan-tilt unit, objects and areas can be scanned. This paper describes the triangulation-maximization leak-localizing strategy (Tri-Max) used in the project RoboGasInspector. Results based on outdoor experiments in two industrial plants and a landfill dump are presented.

    Andreas Kroll Computational Intelligence - Eine Einführung in Probleme Methoden und technische Anwendungen 2013 Oldenbourg Verlag, München, 428 Seiten  URL  
    Abstract: Das erste deutschsprachige Lehrbuch zum Thema Computational Intelligence für Ingenieure. Beschreibung, Analyse und Entwurf technischer Systeme werden zunehmend komplexer und erfordern neuartige Lösungsansätze. Durch die Natur inspiriert entstanden verschiedene Berechnungsverfahren, die im Wissenschaftsgebiet der Computational Intelligence (CI) zusammengefasst sind. Hierzu zählen die etablierten Kernbereiche der Fuzzy-Systeme, Künstliche Neuronale Netze und Evolutionäre Algorithmen sowie aus diesen zusammengeführte Hybride Methoden. Hinzu kommen die noch jungen Gebiete der Schwarmintelligenz und der künstlichen Immunsysteme. So bewegt sich die CI an der Schnittstelle zwischen Ingenieurswissenschaften und Informatik. Dieses Buch bietet eine gut verständliche, vereinheitlichende und anwendungsorientierte Einführung in das Thema und vermittelt Studenten und berufstätigen Ingenieuren das notwendige Fachwissen. Neben den methodischen Erläuterungen sind einfach nachvollziehbare Beispiele integriert, die die Funktion der Methoden veranschaulichen. Darüber hinaus wurden Praxisbeispiele zur Illustration der praktischen Relevanz aufgenommen.

    Abstract: Detection and localization of escaped hazardous gases is of great industrial and public interest in order to prevent harm to humans, nature and assets or just to prevent financial losses. The development of novel leak-detection technologies will yield better coverage of inspected objects while helping to lower plant operation costs at the same time. Moreover, inspection personnel can be relieved from repetitive work and focus on value-adding supervisory control and optimization tasks. The proposed system consists of autonomous mobile inspection robots that are equipped with several remote gas sensing devices and local intelligence. Chain-driven all-terrain robots are used that can handle slopes, unpaved routes and offer maneuverability in restricted spaces as required for inspecting plants such as petroleum refineries, tank farms or chemical sites. The robots can detect and locate gas leaks autonomously to a great extent using infrared optical spectroscopic and thermal remote sensing techniques and data processing. This article gives an overview of the components of the robotic system prototype, i.e. the robotic platform and the remote sensing and evaluation module. The software architecture, including the robot middleware and the measurement routines, are described. Results from testing autonomous mobility and object inspection functions in a large test course are presented.

    Samuel Soldan, Gero Bonow, Andreas Kroll RoboGasInspector - A Mobile Robotic System for Remote Leak Sensing and Localization in Large Industrial Environments: Overview and First Results 2012 Proceedings of the 2012 IFAC Workshop on Automatic Control in Offshore Oil and Gas Production, pp. 33-38, Norwegian University of Science and Technology, Trondheim, Norway,, 31.05 - 01.06.  URL  
    Abstract: In order to automate the routine inspections in large industrial environments a mobile robotic system is being developed in the project RoboGasInspector. The robot's sensor-head consists of different instruments for remote sensing using multiple measurement principles. First results show that passive IRthermographic imaging can be used to detect leaks in pipes as well as liquid spills on the ground. The measurable effects are the temperature profile disturbance due to expansion of pressured gas and evaporative cooling, respectively. Tunable Diode Laser Absorption Spectroscopy (TDLAS) measurement systems provide for quantitative gas concentration measurements and feature a high sensitivity due to the active measurement principle. On the contrary, TDLAS systems measure just the concentration along a path at a time and require a diffusely reflecting background. Using a Pan-Tilt Unit, objects/areas can be scanned and discrete maps of the gas concentration can be created. This contribution introduces the project RoboGasInspector and presents the used measurement technology as well as first results

    Abstract: Eine regelmäßige und sorgfältige Inspektion von druckführenden Komponenten in Industrieanlagen (z. B. Mineralölraffinerien oder Chemieanlagen) ermöglicht ein frühzeitiges Erkennen von möglichen Störungen und Defekten und gewährleistet dadurch eine Betriebssicherheit auf hohem Niveau. Routineinspektionen werden oft nur mit einfachen lokal messenden Gasmessgeräten durchgeführt und sind durch wechselnde Inspekteure und Schichtarbeit personen- und tagesformabhängig. Dabei ist die Inspektionstätigkeit zumeist monoton und ermüdend. Die hohen Anschaffungskosten, die notwendige umfangreiche Einarbeitung in die Bedienung, die niedrige Auslastung bei manueller Verwendung sowie das schwer quantifizierbare Einsparungspotential schrecken oft von der Beschaffung von Fernmessgeräten ab. Ziel des Projektes RoboGasInspector ist die Entwicklung eines mobilen, mit infrarotoptischer Fernmesstechnik ausgestatteten professionellen Service-Roboters für die Routineinspektion von Industrieanlagen. Durch den Einsatz auf einem Roboter kann die Messtechnik voll ausgelastet werden, da dieser rund um die Uhr im Betrieb sein kann. Der Mensch wird von eintöniger Arbeit entlastet und das Fachpersonal steht für anspruchsvollere Aufgaben zur Verfügung. Die Reproduzierbarkeit der Ergebnisse wird verbessert und lässt zudem eine präzisere Differentialdiagnose mit historischen Daten zu; dadurch kann auch der Schädigungsverlauf dokumentiert werden. Durch die Verwendung von Messgeräten mit verschiedenen Messprinzipien kann eine Leckhypothese abgesichert und die Wahrscheinlichkeit von Falschalarmen reduziert werden. Die Interoperabilität der verschiedenen Messgeräte und deren modularer, mechanischer und elektrischer, spritzwassergeschützter Aufbau auf einer mobilen Roboterplattform wird in diesem Beitrag diskutiert und mit praktischen Erfahrungen zur Leistungsfähigkeit des Systems abgerundet. Dazu wurde ein modulares Messsystem entworfen, prototypisch realisiert und im Labor getestet. Das System verfügt über eigene Rechenkapazität und fasst die unterschiedlichen Schnittstellen sowie die Messdatenerfassung der Messgeräte zusammen. Dies vereinfacht somit die Verwendung des Systems auf verschiedenen Roboterplattformen.

    Abstract: Industrial plants are a vital and common asset of modern society in a various number of ways. Safety of large industrial complexes that handle hazardous chemical materials is of utter importance to prevent harm to employees, general population, our natural environment and valuable infrastructure. Therefore, beside the plant owner's own financial interest to guarantee faultless and safe operation, legal regulations have to be adhered due to strong public interest as well. An important measure to ensure safety is the implementation of regular inspection tours by maintenance personnel, who examine the often widely-stretched process infrastructure on foot and locally search for signs of beginning leakage. The Research Project RoboGasInspector was started to develop new means of aiding with the fulfillment of this essential task. This article gives an insight into this ongoing research project, where autonomous mobile robotics is combined with laser-based remote gas detection technology in order to create a proof-of-concept inspection system prototype, which can relieve humans of this monotonous and highly repetitive work.

    Schrodt, Alexander, Kroll, Andreas Zur Fuzzy-Clusterungs-basierten Identifikation eines Verbrennungsmotorkennfelds: Methodenvergleich und Parametrierungsstrategie 2011 21. Workshop Computational Intelligence, pp. 47 - 60, Schriftenreihe des Instituts für Angewandte Informatik / Automatisierungstechnik, Dortmund, 1.-2. Dezember   
    Abstract: Für eine präzise Modellerstellung ist es unerlässlich, die Auswirkungen des Entwurfsverfahrens auf das entstehende Modell genau zu kennen, wobei das Ergebnis i. d. R. entscheidend durch vom Benutzer festzulegende Entwurfsparameter beeinflusst wird. Besonders interessant für eine (teil-)automatisierte Systemidentifikation ist die Klasse der clusterungsbasierten Identifikationsverfahren (unter anderem [1, 2]) mit Takagi-Sugeno- Fuzzy-Modellen (TS). Dies liegt unter anderem daran, dass TS-Modelle als universelle Approximatoren alle stetigen Systeme beliebig genau nachbilden können. Außerdem können lokale Teilmodelle, bei entsprechender Parameterwahl, als lokale Linearisierungen interpretiert werden [3, 4]. Die wichtigsten Entwurfsparameter für Fuzzy-Clusterungsverfahren sind der Unschärfeparameter m und die Clusteranzahl c. Weiterhin unterscheiden sich die Verfahren durch verschiedene Formmatrizen A der Abstandsnormen. In der Literatur findet die Wahl insbesondere des Unschärfeparameters m in Bezug auf Systemidentifikation recht wenig Beachtung. So wird meist ein Wert von m = 2 verwendet (unter anderem in [2, 3]), welcher nicht unbedingt ideal für die Systemidentifikation ist [5, 6]. In der jüngeren Literatur finden sich zwar Beispiele für die Untersuchung des Unschärfeparameters bei der Clusterung (unter anderem [6, 7, 8, 9, 10]). Allerdings beziehen sich die Untersuchungen nur zu geringem Teil auf Systemidentifikation, sondern eher auf reine Clusterung [7] oder Mustererkennungsaufgaben [10]. Im Beitrag wird die Effektivität und Effizienz verschiedener clusterungsbasierter TS-Identifikations- Verfahren sowie der Einfluss der Entwurfsparameter am Beispiel einer nichtlinearen Regressionsaufgabe untersucht. Dabei werden TS-Modelle eines stark nichtlinearen Motorkennfelds (Helixform, Bild 2) mit drei Eingangs- und einer Ausgangsgröße aus Messungen am Prüfstand (Bild 1) ermittelt und verglichen. Es wird gezeigt und begründet, dass eine Wahl von m = 2 ungünstig ist und Werte von 1 < m 1,5 zu guten Ergebnissen führen.

    Abstract: In data fusion of imaging sources the knowledge about the intrinsic and extrinsic parameters of the camera is essential to avoid correspondence problems (i.e. matching up the corresponding points of two images acquired with some displacement disparity). A common way to determine these parameters is the use of a calibration board with known characteristics that is placed at different orientations in front of the camera. For normal cameras in the visible spectrum simple planar patterns in black and white color (like chessboards or dots in a grid arrangement) have been used as test fields with great success. For thermal cameras however these calibration targets don&#x27;t work due to the even thermal distribution. This poster is motivated by an inspection task in an unknown environment where the fusion of data from a thermography camera, a normal camera and a laser range finder is desired. The correspondence problem is stated and a structured overview of different calibration boards that have been used for geometric calibration of thermography cameras in literature is presented. All these solutions seem to be unnecessarily complicated for a one-time calibration. Therefore own ideas and experimental results with a simple and cheap calibration board that provides sufficient accuracy are provided.

    Kroll, Andreas, Dürrbaum, Axel On Control-specific Derivation of Affine Takagi-Sugeno Models from Physical Models: Assessment Criteria and Modeling Procedure 2011 CICA 2011 IEEE Symposium on Computational Intelligence in Control and Automation, pp. 23 - 30, Paris, France, IEEE Symposium Series on Computational Intelligence, April 11-15  URL  
    Abstract: Models are commonly derived and their performance is assessed wrt. minimal prediction error on a closed data set. However, if no perfect model can be used, the degrees of freedom in modeling should be used to adjust the model to application-specific metrics. For model-based controller design, control-oriented performance metrics (e.g. performance wrt. to control-critical properties) are important, but not primarily prediction (i.e. prognosis- and simulation-oriented) ones. This motivates the derivation of control-specific models. The contribution introduces structured and quantitative measures on &quot;model suitability for control&quot; for the class of affine dynamic Takagi-Sugeno models. A method is suggested that derives control-specific dynamic models from a physical model given as a set of nonlinear differential equations. Within a case study, the proposed method demonstrates its significance: Using control-specific models improves control performance metrics such as set-point tracking quality, stability region and energy efficiency.

    Abstract: Die Erstellung und Bewertung von Modellen orientiert sich i. d. R. am Prädiktionsfehler oder an der Approximationsgüte unabhängig vom Einsatzzweck eines Modells. Dies liegt an den üblichen Methoden sowie daran, dass Modellbildung und Reglerentwurf häuffig von unterschiedlichen Spezialisten durchgeführt werden. Da selten ein exaktes Modell erstellt werden kann, sollten die Freiheitsgrade bei der Modellbildung genutzt werden, um ein für die geplante Anwendung optimiertes Modell zu erhalten. Beim modellbasierten Reglerentwurf ist die Prädiktionsgüte eines Modells kein primäres Kriterium; vielmehr sollte das Modell gut für den Reglerentwurf geeignet sein. Diese Einsicht führte im Bereich der linearen Systemidentidentifikation zu neuen Methoden. In diesem Beitrag wird eine Methodik zur Ableitung regelungsorientierter Takagi-Sugeno-Fuzzy-Modelle aus physikalischen Modellen vorgestellt und am Benchmark-Beispiel des inversen Pendes demonstriert.

    Abstract: In case of a structural mismatch between a Takagi-Sugeno model and a nonlinear system that is to be modelled, identification algorithms tend to compensate this by a finer granular partitioning. This is in conflict with the objective of parsimonious models. A novel TS model type with multi-dimensional fuzzy sets and locally adjustable/heterogeneous fuzziness is presented with a method for the adjustment. This new approach enhances the structural flexibility of the model while the number of parameters increases negligibly. Two case studies, including compressor modelling, illustrate the performance of the proposed method.

    Andreas Kroll On choosing the fuzziness parameter for identifying TS models with multidimensional membership functions 2011 Journal of Artificial Intelligence and Soft Computing Research, vol. 1, no. 4, pp. 283-300  URL  
    Abstract: Fuzzy clustering is a well-established method for identifying the structure/fuzzy partitioning of Takagi-Sugeno (TS) fuzzy models. The clustering algorithms require choosing the fuzziness parameter m. Prior work in the area of pattern recognition shows, that a suitable choice of m is application-dependent. Yet, the default of m=2 is commonly chosen. This paper examines the suitable choice of m for identifying TS models. The focus is on models that use the classifiers resulting from fuzzy clustering as multi-dimensional membership functions or their projection and approximation. At first, the differentiability and grouping properties of the fuzzy classifiers are analyzed to make a general recommendation of choosing m(1;3). Besides, the effect of the cluster number c on the classification fuzziness is examined. Finally, requirements that are specific to TS modeling are introduced, which narrow down the suitable range for m. Building on algorithm analysis and four case studies (function approximation, a vehicle engine and an axial compressor application for nonlinear regression), it is demonstrated that choosing m(1;1.3) for local and mâ(1;1.5) for global estimation will typically provide for good results.

Conf. on NDE in Relation to Structural Integrity for Nuclear and Pressurised Components, pp. 503-512, European Commission, Joint Research Center, Institute for Energy, Berlin, Germany, DGZfP-Proceedings BB 125-CD, 29. September - 1. Oktober  URL  
    Abstract: Detection of leaks in pressurized components such as above-ground pipes, vessels, instruments, fittings and machinery is of high relevance for plant operating authorities and utility companies in order to prevent harm to humans, nature and assets or just to prevent financial losses. Especially for gaseous fluids, remotely applicable infrared (IR) spectroscopical detection methods can be applied to scan the environment of the pressurised components for escaped gas. Spectroscopic methods fail if the spectral fingerprint of the fluid is unknown or not distinguishable in the chosen IR window of the atmosphere. Moreover, leaks in pressurised or liquid air leading components cannot be detected spectroscopically. In such cases, the application of passive IR thermography is proposed to permit remote leak detection by assessing the resulting temperature profile disturbance due to the cooling effect of expanding gas. This effect is not limited to pressurised air but can be used for any gaseous fluid. The thermal effect is tiny and the disturbances e.g. due to reflections of natural and artificial IR emitters and due to varying surface and material properties (heat conduction, emissivity, reflectivity,...) in the optical infrared spectral region make it difficult to interpret the interferogram by the human operator to identify a leak. In this contribution, methods for an automatic analysis of thermograms with respect to the presence of leaks by using pattern matching algorithms are presented. For this purpose, a dedicated test stand was build. The results of extensive leakage measurement campaigns with different materials (incl. ordinary and stainless steel), various pressurized components (incl. pipes, valves, flanges, manometers) and of different measurement set-ups (measurement angle, disturbing emitters, pressure difference, ...) will be presented. Pressurised air was used as test gas due to its simple handling. Different pattern matching algorithms that use the concept of a matching filter will be introduced and first results comparing their classification performance will be recorded. It will be shown, that under laboratory conditions, an extended range of leakages can be reliably detected.

    Abstract: In this paper an observer-based fault detection approach for a class of nonlinear systems, which can be modeled by Takagi-Sugeno (TS) fuzzy models, is presented. We propose a sliding mode fuzzy observer that deals with bounded uncertainties in the plant and allows fault estimation based on an equivalent output error injection approach. Necessary conditions for the existence of the robust observer are derived from sliding mode theory . Stability is ensured by linear matrix inequality (LMI) based sufficient conditions. An illustrative example demonstrates the effectiveness of the proposed scheme.

Necessary conditions for the existence of the robust observer are derived from sliding mode theory . Stability is ensured by linear matrix inequality (LMI) based sufficient conditions.

    Abstract: In this paper, an observer-based fault detection approach for a class of nonlinear systems is presented, which can be modeled by Takagi-Sugeno (TS) fuzzy models. We propose a sliding mode fuzzy observer that deals with bounded uncertainties in the plant and allows fault estimation based on an equivalent output error injection approach [5]. Furthermore an adaption scheme based on pattern recognition algorithms is presented. It allows to deal with situational uncertainties, which affect the system, by adapting the fault sensitivity. An extensive simulation of a mobile working machine is used to demonstrate the effectiveness of the proposed scheme.

    Abstract: Frequently, the increasing level of automation requires a systematic consideration of numerous interacting components influenced by internal feedback mechanisms as well as interactions with human operators under varying environmental conditions. This places demands on modeling, which in general cannot be satisfied by traditional modeling concepts. In this paper, a model approach for complex technical systems is developed, which consists of two language layers. The first layer takes the physical knowledge of the technical system into account. The second one uses stochastic models in combination with superordinate higher-level terms to formulate properties concerning the overall system. By means of a case study dealing with the automation of mobile working machines, it is shown that this approach can be used to recognize driving situations under varying environmental conditions.
