摘要：

 本文基于线性矩阵不等式(LMI)理论研究一类具有不确定和时滞的线性离散切换系统的二次稳定保成本控制问题. 利用多Lyapunov函数构造线性矩阵不等式，基于状态的切换规则给出了这类系统二次稳定保成本控制的充分条件，以及切换规则和切换控制器的设计方案. 数值计算验证了文中结果的有效性.

Abstract:

This paper addresses quadratic stability guaranteed cost control for a class of linear discrete-time switched systems with uncertain multiple time-delays in state and input based on LMI theory. By using multiple Lyapunov functions and constructing linear matrix inequalities, several sufficient conditions for the problem under study is derived with a state-based switching law. Controllers of the subsystems are designed and the switching law obtained simultaneously. A numerical example shows effectiveness of the method.

Key words: switched systems, time-delays, stability, feedback, matrix inequality
