　　Abstract : D- stable fault- tolerant control problem is studied for discrete systems with a time delay , which can guarantee some performance after sensor failures . A sufficient condition for D- stable control systems possessing integrity against sensor failures is presented. Then the D- stable robust fault- tolerant control problem is studied for uncertain discrete time- delay systems . The design method of D- stable robust fault- tolerant control systems is given , and the results are extended to the situation of ac2 tuator failures . Finally , an illustrative example and simulation results are given to demonstrate the effectiveness of the proposed method.
Key words : fault- tolerant control ; D- stability ; time- delay systems ; robustness ; discrete systems
