摘　　要： 针对利用模糊T-S模型建模的切换模糊系统,考虑当系统同时存在不确定和时滞的情况下,研究系统的状态反馈控制问题。利用切换技术和多Lyapunov函数方法,给出状态反馈控制器存在的充分条件,相应结果以矩阵不等式形式给出,并给出切换律设计。利用平行分布补偿算法(PDC),给出切换模糊状态反馈控制器设计,使得闭环系统在所设计的控制器和切换律下,对所有允许的不确定具有鲁棒性。仿真结果表明方法的有效性。 The robust feedback control problem is studied for a class of switched fuzzy systems based on fuzzy T-S model with the uncertainty and time-delay simultaneously.The existance sufficient conditions for state-feedback controller are presented by using the switching technique and the multiple Lyapunov function method.Corresponding results are obtained through matrix inequality,and the design of switched law is given.Based on the parallel distributed compensation,the switched fuzzy state-feedback controller is designed.The closed-loop system has robustness for all admissible uncertainties,and is globally asymptotically stable under the proposed controller and switched law.Simulation results show the effectiveness of the design method.
