Robust Fault-tolerant Control Studies of State and Control Time-delay System Based on T-S Fuzzy Model

摘要：

The problem of robust fault-tolerant control for the uncertain time-delay system was investigated by utilizing the fuzzy control method. Constructing T-S model and introducing parametric uncertainty and time-delay terms for the systems, there made the fuzzy model approach to the original system more exactly. Based on T-S Fuzzy Model, Lyapunov stability theory and Linear Matrix Inequality (LMI), a method of robust fault-tolerant control against sensor or actuator failures for uncertain systems was proposed via memoryless state feedback control law. The sufficient conditions for the closed-loop system possessing integrity against sensor or actuator failures were given. The results of fault-tolerant controller could be involved by solving several Linear matrix inequalities. Finally, the simulation results illustrate the effectiveness of the proposed approach.
