Application to Fault Detection

Research into condition monitoring, or fault detection and diagnosis, for dynamic systems has long been recognised as one of the important aspects in seeking effective solutions to an improved reliability of practical control systems. As a result, many methods have been developed in the past two decades. In general, these approaches can be classified into the following three groups: i) Observer based fault detection and diagnosis for systems whose models are almost known; ii) Identification based fault detection and diagnosis for systems whose models are unknown; iii) Unexpected change detection for stochastic signals.
