Abstract:
Based on T-S fuzzy model,the problems of guaranteed cost fault tolerant control for a class of uncertain nonlinear time-delay systems with actuator failures are studied.A sufficient condition for the existence of state feedback guaranteed cost fault controller is given in terms of the liner matrix inequality(LMI).All allowable uncertain systems are guaranteed to be stable.Closed-loop system with actuator failures is of asymptotic stability.For a given quadratic cost function,the cost is bounded in a range.A simulation example shows the effectiveness of the design method.
