The sufficient condition to guarantee the robust stability of a class of discrete delay uncertain systems is proposed by using Lyapunov method,and then a state feedback robust controller is designed based on the linear matrix inequalities (LMI) technique. A simulation example is provided to show the correctness and the effectiveness of the proposed method.%对范数有界不确定离散时滞系统,给出了鲁棒稳定性判定标准,构造相应的Lyapunov函数.采用线性矩阵不等式(LMI)技术,设计出基于LMI的状态反馈鲁棒控制器.通过仿真实例验证了该方法的正确性和有效性.
