Aiming at a class of nonlinear systems and strict dissipation requirements with norm bounded time-varying parameter uncertainty represented by T-S fuzzy model, a robust dissipative fault-tolerant controller design method with stable and strictly dissipated system during actuator failure is proposed. Applying the parallel distributed control and linear matrix inequality methods, the sufficient conditions for the existence of the fault-tolerant controller in the system dissipated in the event of actuator failure are obtained, and the closed-loop system is robust to the allowable parameter uncertainty. The convex optimization problem of linear matrix inequality constraint is further established and solved, and the design method of fuzzy fault-tolerant controller with stable and strict dissipation system is given. The simulation results show the feasibility and effectiveness of the proposed method.
