摘　　要：研究了一类不确定时滞切换组合大系统的分散控制问题.对于复杂的切换组合时滞大系统,在每一个小子系统均不能被镇定的情况下,运用切换技术,凸组合技术和李亚普诺夫函数方法设计了鲁棒分散状态反馈控制器和相应的分散切换策略,使得不确定切换组合时滞大系统可以渐近镇定.In this paper, the authors study the design of decentralized switching law for uncertain time-delay switched composite large scale systems. Based on convex combination technique and LMI method, decentralized state feedback controllers and decentralized switching law are designed to make the closed-loop systems be asymptotically stable under the assumption that each uncertain subsystems can＇ t be stabilized. The sufficient condition for the solution to the problem is presented in term of LMI. A numerical example is provided to demonstrate the validity of the proposed design approach.
