英文摘要：

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.
