摘　　要：针对一类多输入多输出(MIMO)网络控制系统,提出一种时滞相关鲁棒控制器的设计方法。首先经过等价推导,将系统转化成具有多输入时滞的连续系统,利用李雅普诺夫函数,通过求解若干线性矩阵不等式,获得系统时滞相关鲁棒控制器。算法递推简单,避免了进行系统变换和处理交叉项,减少了计算负荷。仿真结果表明:在网络具有一定传输时延的情况下,该方法可以获得满足系统稳定性的控制器。As for a class of MIMO networked control systems,a delay-dependent robust controller design method was proposed.Firstly,a continuous system with multiple input delays was obtained through equipollent deduction.And then,using Lyapunov function and by solving some linear matrix inequality,a delay-dependent robust controller was designed which could make deduction simple,and avoid model transformation and deal with cross form,which meant less calculation.The simulation shows it is useful to get the robust controller when the networked-induced delays satisfied some bound.
