| 摘 要： | 针对一类时变不确定、参数有界且状态多时滞离散系统,给出了鲁棒稳定性新的充分条件。通过构造Lyapunov函数,仅需求解一个线性矩阵不等式(LMI),就可设计出保证闭环系统稳定的状态反馈鲁棒控制器。最后通过数值例子说明了该方法的正确性和有效性。

| Abstract: | Focusing on a class of discrete-time systems with norm-bounded uncertain and state multiple delays, this paper presents new criterias, which are expressed in terms of linear matrix inequalities(LMIs), for robust stability of the system. By using Lyapunov method, this article designs a state feedback robust controller to guarantee asymptotic stability of the closed-loop system. A simulation case is provided to illustrate the correctness and the effectiveness of the proposed theoretical results. |
