英文摘要

      In this paper， on the basis of Lyapunov stability theory and linear transformation techniques， the problem of D-stable robust fault-tolerant control for discrete systems is studied. A sufficient condition that D-stable system possessing integrity against sensor failures is given. Then D-stable robust fault-tolerant control problem of uncertain discrete system is discussed， and develop the results to actuator failure case. De-sign method of D-stable robust fault-tolerant control system is given. Finally， an illustrative example and sim-ulation results are given to demonstrate the effectiveness of the design method proposed in this paper.
