Beschreibung
Fault-tolerant control aims at graceful degradation of automated systems in case of faults. It satisfies the industrial demand for enhanced availability and safety, in contrast to traditional reactions to faults that bring about sudden shutdowns and loss of availability. The book presents effective model-based analysis and design methods for fault diagnosis and fault-tolerant control. Architectural and structural models are used to analyse the propagation of the fault through the process, to test the fault detectability and to find the redundancies in the process that can be used to ensure fault tolerance. Design methods for diagnostic systems and fault-tolerant controllers are presented for processes that are described by analytical models, by discrete-event models or that can be dealt with as quantised systems. Four case studies on pilot processes show the applicability of the presented methods. The theoretical results are illustrated by two running examples which are used throughout the book.The book addresses engineering students, engineers in industry and researchers who wish to get a survey over the variety of approaches to process diagnosis and fault-tolerant control.
Technological systems are vulnerable to faults. Actuator faults reduce the performance of control systems and may even cause a complete break-down of the system. Erroneous sensor readings are the reason for operating points that are far from the optimal ones. Wear reduces the efficiency and quality of a production line. In most fault situations, the system operation has to be stopped to avoid damage to machinery and humans. As a consequence, the detection and the handling of faults play an increas ing role in modern technology, where many highly automated components interact in a complex way and where a fault in a single component may cause the malfunction of the whole system. Due to the simultaneously increasing economic demands and the numerous ecological and safety restrictions to be met, high dependability of technological systems has become a dominant goal in industry in the recent years. This book introduces the main ideas of fault diagnosis and fault-tolerant control. It gives a thorough survey of the new methods that have been de veloped in the recent years and demonstrates them by application examples. To the knowledge of the authors, all major aspects of fault-tolerant control are treated for the first time in a single book from a common viewpoint.

From the reviews:
"The book by Blanke et. al covers several model-based failure detection techniques. … A large portion of the book is devoted to presenting alternative modeling techniques. … the book is suited for those who want to begin researching failure detection and want to learn about some of the ideas examined recently in the literature." (IEEE Control Systems Magazine, Vol. 25 (1), February, 2005)
"There are many processes where overall failure would be expensive or even catastrophic and there is reason to use one of the techniques described in this book. … Some of the material is in fact published here for the first time. … The book under review must clearly be unrivalled as the standard textbook and reference source in its field." (Robotica, Vol. 22, 2004)
"The book introduces the main ideas of fault diagnosis and fault-tolerant control. It gives a systematic survey of the new methods that have been developed in recent years and illustrates them by application examples. It is important to mention that all major aspects of fault-tolerant control are treated for the first time in a single book from a common viewpoint. … With respect to fault accommodation and control reconfiguration, the book presents the current state of the art." (Tzvetan Semerdjiev, Zentralblatt MATH, Vol. 1023, 2003)
