This paper considers Robust Fault Detection and Isolation Observer (RDO) design for singular system with faults. Using observer-based approaches to the RDO problem, three types of faults are considered in a unified manner. Necessary and sufficient conditions for the existence of RDO and a design algorithm are given.
Keywords: fault detection, fault diagnosis, observers, singular systems, robustnees
