摘　　要：研究了状态及控制均存在常数时滞和不确定性参数满足一定有界条件的一类线性滞后型系统的H∞控制问题.通过求LMI,不但可得镇定该系统的控制器,而且使其闭环系统的H∞范数小于某一给定的上界。The problems of H∞ control for a class of uncertain structural linear systems with time-delay in both constant and controlled state are analyzed. By solving LMI, this research not only obtains the stability controller for the systems but also make the H∞ norm of dosed-loop system to be less than a given upper bound.

关 键 词：不确定时滞系统 线性矩阵不等式 H∞控制
