Robust H∞ tolerant control for a class of discrete systems with time delays based on T-S fuzzy models

The problems of robust H_infin tolerant control for a class of discrete systems with state and time delays and actuator faults are studied. The T-S fuzzy model with time delays is adopted to repress a class of discrete systems. By established actuator fault model, the state feedback controller is designed. A sufficient condition for the asymptotic stability of closed-loop system is given based on Lyapunov stability theory and linear matrix inequality method, which can guarantee robust stability of system with actuator faults and disturbances. Simulation results show the effectiveness of the proposed approach.
