摘　　要：讨论含饱和驱动的线性时滞系统的时滞相关鲁棒稳定化以及控制器的设计问题.借助于积分不等式,利用Lyapunov_Krasovskii泛函方法,结合S_过程,获得了基于LMI的可稳定化的时滞相关条件,同时给出了无记忆控制器的设计方法,不必对原系统进行任何模型变换.实例表明,本文方法所得结论具有较小的保守性.The delay-dependent robust stabilization of the systems with saturating actuator is discussed. Based on an integral inequality ,some new delay-dependent criteria are obtained by using Lyapunov-Krasovskii functional method incorating with S-procedure, which can guarantee the asymptotical stability of the closed-loop systems via memoryless state feedback. There is no any model transformation required, Finally, a numerical example is given to illustrate that the new results are of less conservativeness than the present ones in literature.
