Abstract: With the continuous increase in complexity and expense of industrial systems, there is less tolerance for performance degradation, productivity decrease, and safety hazards, which greatly necessitates to detect and identify any kinds of potential abnormalities and faults as early as possible and implement real-time fault-tolerant operation for minimizing performance degradation and avoiding dangerous situations. During the last four decades, fruitful results have been reported about fault diagnosis and fault-tolerant control methods and their applications in a variety of engineering systems. The three-part survey paper aims to give a comprehensive review of real-time fault diagnosis and fault-tolerant control, with particular attention on the results reported in the last decade. In this paper, fault diagnosis approaches and their applications are comprehensively reviewed from model- and signal-based perspectives, respectively.

TL;DR: The approach to failure diagnosis presented in this paper is applicable to systems that fall naturally in the class of DES's; moreover, for the purpose of diagnosis, most continuous variable dynamic systems can be viewed as DES's at a higher level of abstraction.
Abstract: Fault detection and isolation is a crucial and challenging task in the automatic control of large complex systems We propose a discrete-event system (DES) approach to the problem of failure diagnosis We introduce two related notions of diagnosability of DES's in the framework of formal languages and compare diagnosability with the related notions of observability and invertibility We present a systematic procedure for detection and isolation of failure events using diagnosers and provide necessary and sufficient conditions for a language to be diagnosable The diagnoser performs diagnostics using online observations of the system behavior; it is also used to state and verify off-line the necessary and sufficient conditions for diagnosability These conditions are stated on the diagnoser or variations thereof The approach to failure diagnosis presented in this paper is applicable to systems that fall naturally in the class of DES's; moreover, for the purpose of diagnosis, most continuous variable dynamic systems can be viewed as DES's at a higher level of abstraction >

TL;DR: In this article, two approaches to fault detection in robotic systems have been discussed: the first approach consists of the use of a linear Luenberger state observer, which generates a robust residual that is maximally sensitive to the faults that have to he detected while remaining unsensitive to the neglected non-linearities.

TL;DR: In this article, a fault detection and isolation problem for both actuator faults and sensor faults of an aircraft is developed for both sensor and actuator failures, and the fault detection filter design is treated as an eigensystem assignment problem.
Abstract: The fault detection and isolation problem is developed for both actuator faults and sensor faults of an aircraft. Pertinent theorems and definitions are presented. The fault detection filter design is treated as an eigensystem assignment problem. A computer algorithm which calculates the detection filters is discussed. Detection filter gains are developed for a linear aircraft model which augments actuator dynamics and a simplified wind gust model. A simulation of various faults and the performance of the detection filters are developed. Results indicate potential for improving fault-tolerant control system designs.
