摘　　要：基于二次稳定性理论,研究了不确定离散时滞系统的鲁棒H∞控制问题.采用线性矩阵不等式的方法,讨论了有记忆状态反馈鲁棒H∞控制问题,得到了确保鲁棒H∞控制器存在的充分条件和H∞状态反馈控制器的设计方法.最后举例说明了该方法的正确性.Based on the quadratic stability theory, the robust Hoo control problem for uncertain discrete-time systems with timedelay was deal with. The problem of robust Hoo control with memory state feedback was discussed by linear matrix inequality approach. The sufficient condition for a robust Hoo controller was derived. An Hoo state feedback controller was designed and the con- troller could be solved by one LMI. An illustrative example was presented to prove the correctness of this method.
