【摘要】研究了一类不确定离散多时滞系统的鲁棒H∞控制问题.针对具有多状态时滞和不确定参数的离散系统,利用Lyapunov稳定性理论和线性矩阵不等式方法,设计无记忆鲁棒H∞状态反馈控制器,给出了状态反馈控制器的设计方法和闭环时滞系统渐近稳定且满足给定H∞性能指标的充分条件.最后,通过MATLAB仿真算例结果验证了该方法的有效性和可行性.%This paper researched the problem on robust H∞ control for a class of uncertain systems with multiple time-delay. For discrete-time systems with multiple state time-delay and uncertain parameter, by using Lyapunov function and LMI, derived state feedback controller design method and a sufficient condition for closed loop time-delay systems which was subject to the asymptotic stability and H∞ performance index. Finally, simulation results of an example with MATLAB show the effectiveness and feasibility of the proposed method. 【总页数】3页(4577-4579)
