TLDR
A number of methods for detecting abrupt changes (such as failures) in stochastic dynamical systems are surveyed in this paper, where tradeoffs in complexity versus performance are discussed, ranging from the design of specific failure-sensitive filters, to the use of statistical tests on filter innovations, and the development of jump process formulations.
Abstract
A number of methods for detecting abrupt changes (such as failures) in stochastic dynamical systems are surveyed. The class of linear systems is concentrated on but the basic concepts, if not the detailed analyses, carry over to other classes of systems. The methods surveyed range from the design of specific failure-sensitive filters, to the use of statistical tests on filter innovations, to the development of jump process formulations. Tradeoffs in complexity versus performance are discussed.

Input design for detection of abrupt changes in dynamical systems

TL;DR: The detection and diagnosis of changes in stationary dynamical systems via statistical methods and using input design to improve detection performance are discussed and the design techniques are extended to the general multiple-hypotheses case.

Fault diagnosis of an intelligent hydraulic pump based on a nonlinear unknown input observer

TL;DR: In this article, a fault diagnosis method of an intelligent hydraulic pump system (IHPS) based on a nonlinear unknown input observer (NUIO) is proposed, which can accurately diagnose and isolate those typical failure modes of the nonlinear IHPS.

On the effect of communication delays in failure diagnosis of decentralized discrete event systems

TL;DR: Conditions on the system structure under which the modified protocols perform as well as the centralized diagnostic scheme proposed in Sampath et al. (1995) are discovered.

Survey paper: Re-thinking diagnosis for future automation systems: An analysis of current diagnostic practices and their applicability in emerging IT based production paradigms

TL;DR: The emerging IT-based production paradigms are surveyed as well as the existing diagnostic methods whose adequacy is analysed and the resulting requirements and characteristics are exposed to stress the need for rethinking current diagnostic practices in future automation systems.

Fault‐tolerant control of process systems using communication networks

TL;DR: In this paper, the authors present a methodology for the design of fault-tolerant control systems for chemical plants with distributed interconnected processing units, which is based on a hierarchical architecture that integrates lower-level feedback control of individual units with upper-level logic-based supervisory control over communication networks.
