About this textbook
Supervision, health-monitoring, fault detection, fault diagnosis and fault management play an increasing role for technical processes and vehicles, in order to improve reliability, availability, maintenance and life-time. For safety-related processes fault-tolerant systems with redundancy are required in order to reach comprehensive system integrity.
This book gives an introduction into the field of fault detection, fault diagnosis and fault-tolerant systems with methods which have proven their performance in practical applications. It guides the reader in a structured tutorial style:

• supervision methods, reliability, safety, system integrity and related terminology;
• fault detection with signal-based methods for periodic and stochastic signals;
• fault detection with process model-based methods like parameter estimation, state estimation, parity equations and principal component analysis;
• fault diagnosis with classification and inference methods;
• fault-tolerant systems with hardware and analytical redundancy;
• many practical simulation examples and experimental results for processes like electrical motors, pumps, actuators, sensors and automotive components;
• end-of-chapter exercises for self testing or for practice.
  

The book is dedicated to graduate students of electrical, mechanical, chemical engineering and computer science and for practising engineers.
