基于Lyapunov泛函方法，对存在状态时滞的线性离散不确定系统，给出了滞后相关型无记忆H∞状态反控制器设计方案，通过求解相应的线性矩阵不等式即可求得满足设计要求的控制器．

英文摘要：

Based on Lyapunov functional method, the problem about the delaydependent H∞ memoryless feedback for linear discrete uncertain systems with delayed state is discussed. The controller, which satisfied the requirement of design, can be obtained by solving linear matrix inequality （LMI） .
