Fault tolerance strategy of general nonlinear systems with actuator and sensor fault based on T‐S fuzzy model
Zhixing Han
Abstract:In this paper, a fault estimation (FE) and sliding mode fault tolerance strategy (SMFTS) scheme based on T‐S fuzzy model are proposed for a class of general nonlinear systems (GNS) that encounter actuator and sensor faults and disturbance. A coordinate transformation is introduced to convert sensor fault into actuator fault. Then, a fuzzy perturbation estimator is established to estimate the detailed fault and disturbance information. Then, a SMFTS scheme is proposed to minimize the damage caused by the faults… Show more
