英文摘要：

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.
