英文摘要：

A new optimal fault-tolerant control algorithm is proposed for linear time-varying singular systems.In order to develop an effective scheme to make time-varying systems work normally when faults occur,Riccati matrix equation is used to get the optimal fault-tolerant law for the faulty system.Finally,a numerical example is given to illustrate the validity of the proposed approach.
