Fault-Diagnosis Systems: An Introduction from Fault Detection to Fault Tolerance / Edition 1

by Rolf Isermann

Overview

With increasing demands for efficiency and product quality and progressing integration of automatic control systems in high-cost mechatronic and safety-critical processes, the field of supervision (or monitoring), fault detection and fault diagnosis plays an important role.

The book gives an introduction into advanced methods of fault detection and diagnosis (FDD). After definitions of important terms, the reliability, availability, safety and systems integrity of technical processes is considered. Then fault-detection methods for single signals without models like limit and trend checking and with harmonic and shastic models, like Fourier analysis, correlation and wavelets are treated. This is followed by fault detection with process models using the relationships between signals like parameter estimation, parity equations, observers and principal component analysis. The treated fault-diagnosis methods include classification methods from Bayes classification to neural networks with decision trees and inference methods from approximate reasoning with fuzzy logic to hybrid fuzzy-neuro systems.

Especially for safety-critical processes fault-tolerant systems are required. Basic redundant structures like n-out-of-m systems, cold and hot standby are considered and ways to design fault-tolerant sensors, actuators and control systems are outlined.

Several practical examples for fault detection and diagnosis of DC motor drives, a centrifugal pump, automotive suspension and tire show applications.

About the Author

Rolf Isermann Rolf Isermann studied Mechanical Engineering and obtained the Dr.-Ing. degree in 1965 from the University of Stuttgart. In 1968 he became "Privatdozent" for Automatic Control and since 1972 Professor in Control Engineering at the University of Stuttgart. From 1977-2006 he was Professor for Control Systems and Process Automation at the Institute of Automatic Control of the Darmstadt University of Technology. Since 2006 he is Professor emeritus and is head of the Research Group of Control Systems and Process Automation. R. Isermann received the Dr. h.c. (honoris causa) from L'Université Libre de Bruxelles and from the Polytechnic University in Bucharest. In 1996 he was awarded the “VDE-Ehrenring”, and in 2007 the “VDI-Ehrenmitglied”. The MIT Technology Review Magazine awarded him in 2003 to the Top Ten representatives of emerging Technologies for the field of Mechatronics.
R. Isermann has published books on Modeling of Technical Processes, Process Identification, Digital Control Systems, Adaptive Control Systems, Mechatronic Systems, Fault Diagnosis Systems, Engine Control and Vehicle Drive Dynamics Control. Current research concentrates on the fields of identification and digital control of nonlinear systems, intelligent control and model-based methods of process fault diagnosis with applications to servo systems, fault-tolerant systems, combustion engines, automobiles and mechatronic systems. The research group on combustion engines works on multivariable engine modeling, HiL-simulation, combustion pressure control and fault diagnosis of both, CR-Diesel engines and FSI-gasoline engines. In the vehicle dynamics group present topics are parameter estimation for drive dynamics control, fault detection of sensors, suspensions, tires and brake systems and the development of collision avoidance systems with surrounding sensing and active braking and steering. The first books on system identification were published in German and date back to 1971, 1974, 1988, and 1992.
Since 1975, R. Isermann held several chair positions of IFAC-Technical Committees (International Federation of Automatic Control). In 1996, he was elected as Vice-President of IFAC until 2002. From 2002 to 2008, he was member of the IFAC-Council.
R. Isermann organized several national and international conferences like the 5th IFAC Symposium on Identification in Darmstadt in 1979, the 10th IFAC-World-Congress in Munich 1987, the 1st IFAC-Symposium SAFEPROCESS, Baden-Baden, 1991 and the 1st IFAC-Conference on Mechatronic Systems, Darmstadt, 2000. He also organized the biannual VDI/VDE-Conference AUTOREG (control of vehicles and power trains) from 2002 to 2008.
