Fault-tolerant control for nonlinear systems based on a new stability condition. (Chinese. English summary) Zbl 1223.93067

Summary: The problems of fault-tolerant control for T-S fuzzy system with possible actuator failure are studied. Based on a new stability condition, a sufficient condition for the existence of fault-tolerant controller is given by using the method of LMI while actuators are of fault. Under this condition, the designed controller not only guarantees the asymptotical stability of the closed-loop system but also a performance at an adequate level. The simulation results expatiates the validity of this method.
