Fault Detection and Reconstruction for Singular Bilinear Systems Using Sliding Mode Observers

In this paper, sliding mode observer is applied to solve fault detection and reconstruction problem for singular bilinear systems with input or measurement faults. To detect and isolate faults, a sliding mode observer based approach is proposed. A feed-forward signal is defined and the existence conditions of fault detection and reconstruction are addressed. An illustrative example is given to demonstrate the applicability of the approach.
