摘要
针对参数不确定性多时滞线性系统,基于李雅普诺夫(Lyapunov)稳定性理论和线性矩阵不等式(LMI)方法,在执行器发生故障的情况下,研究系统的鲁棒容错H_∞控制问题。设计鲁棒容错控制器,给出参数不确定性多时滞系统保持渐近稳定的充分条件,以及满足给定性能指标的鲁棒容错控制器的设计方法。仿真算例说明,该方法是有效和可行的。
For a class of uncertain multi-time-delay linear systems, based on the Lyapunov stability theo- ry and linear matrix inequality method, the robust fault-tolerant H∞ control problem is researched when something goes wrong with actuators. A sufficient condition for the systems keeping asymptotically stable is given, and thereby, a robust fault-tolerant controller satisfying the given performance index is de- signed. The simulation results verify the effectiveness and feasibility of the proposed approach.
