针对一类存在时滞的不确定切换模糊系统,研究系统的保性能控制问题。利用平行分布补偿算法(PDC)给出保性能控制器的设计方法,利用单Lyapunov函数方法和多Lyapunov函数方法,给出不确定切换模糊时滞系统保性能控制器存在的充分条件和切换律设计。使得闭环系统对所有允许的不确定,在所设计的控制器和切换律下实现保性能控制。仿真结果表明方法的有效性。
For a class of uncertain switched fuzzy systems with time-delay, the guaranteed cost of the system is studied. Using the parallel distributed compensation algorithm (PDC), the design method of guaranteed cost controller is given. The sufficient conditions and the switching law design for the guaranteed cost guaranteed controller of the fuzzy switched system with time-varying switching are given by using single Lyapunov function method and multiple Lyapunov function method . The closed-loop system is allowed to have all the uncertainties. Under the designed controller and switching law, the guaranteed performance is guaranteed. Simulation results show the effectiveness of the method.
