| Abstract: | Aiming at a class of nonlinear systems with uncertain parts and exterior disturbances described by T-S Fuzzy Models, measuring residual and parityequations are firstly constructed, then robust fault detection and diagnosis on the systems are discussed, and the existing condition and research method of optimal parity vector which is sensitive to special sensor or controller faults is discussed. Finally, the simulation example shows the approach proposed in this paper is effective. |
