摘　　要：针对一类不确定离散切换模糊时滞系统,研究了在控制器增益存在摄动情况下的稳定性问题.利用切换技术和多Lyapunov函数方法,并以矩阵不等式形式给出了非脆弱状态反馈控制器存在的充分条件和切换律设计.最后通过数值仿真算例验证了设计方法的有效性和可行性.This paper investigates the problems of non-fragile control for a class of uncertain discrete switched fuzzy control systems with time-delay. A sufficient condition for the existence of non-fragile state-feedback controllers and the switching law are proposed based on switching and multiple Lyapunov functions technique. The corresponding results are all formulated in terms of matrix inequalities. Finally, an illustrative example shows the feasibility and the effectiveness of the proposed approach.
