摘　　要：研究了一类网络切换模糊时滞系统的容错控制问题。当系统的执行器失效时,利用切换技术和Lyapunov函数方法,给出了各个子系统的状态反馈控制器及切换律的设计。通过预先给定的失效集,使得闭环系统对于发生在给定失效集的执行器失效,在所设计的控制器及切换律下是渐近稳定的。最后,通过仿真例子验证了设计方法的有效性。The problem on fault-tolerant control for a class of network switched fuzzy time-delay systems was studied. When actuators of the system failed, state feedback controllers of each subsystem and the switching law were proposed by application of the switching technique and Lyapunov function method. Through giving failure set in advance, the closed-loop system was made to have actuator of the given failure set fail, and to be asymptotically stable under the given controller and the switching law. Finally, a simulation example was given to demonstrate and verify the effectiveness of the orooosedapproach in design.
