一类网络切换模糊系统的容错控制

Fault-tolerant control for a Class of Network Switched Fuzzy Systems

针对一类网络切换模糊系统,考虑当系统的执行器失效时,利用切换技术和Lyapunov函数方法,给出各个子系统的容错控制器及切换律的设计方法,使得闭环系统对于给定失效集内的执行器失效,在所设计的容错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。

A class of network switched fuzzy system was put into consideration. When actuators of the system failure, fault-tolerant controllers of each subsystem and the switching law were proposed based on switching technique and Lyapunov function method. For a specified given actuator failure set, it guarantees that the closed-loop system is asymptotically stable for actuator failures occurred in a given failure set under the proposed fault-tolerant controller and the switching law. Finally, a simulation example was given to demonstrate the effectiveness of the proposed approach in design.
