摘　　要：研究同时具有时滞和不确定性的一类切换系统的鲁棒镇定问题,控制器的设计采用无记忆状态反馈的形式,所设计的控制器能够保证切换系统在任意切换下都是鲁棒渐近稳定的。通过引入自由权矩阵,降低了结果的保守性,通过构造李亚普诺夫-克拉索夫斯基函数,得到了系统在任意切换下鲁棒镇定的充分条件,该条件可通过变量变换化成线性矩阵不等式的形式而得到其可行解。The delay-dependent robust stabilization analysis of the uncertain switched systems with time-varying delay is studied in this paper.The controllers are designed in the form of memoryless state-feedback and it can guarantee the system to be asymptotically stable under arbitrary switching law.The delay-dependent sufficient condition of robust stabilization is presented by introducing the free weighting matrices and it can be solved by linear matrix inequalities.
