摘 要: 利用混杂反馈控制策略研究一类线性不确定时滞系统H∞鲁棒镇定问题.分别利用单Lyapunov函数方法和多Lyapunov函数方法给出了控制器的两种切换方案,这两种方案都能保证线性不确定时滞系统的镇定和H∞扰动衰减度,并由两个耦合的线性矩阵不等式的解给出了两个静态状态反馈H∞控制器的设计. By means of hybrid feedback control strategy, the problem of H∞ robust stabilization for a class of uncertain linear time-delay systems is studied. Based on single Lyapunov function technique and multiple Lyapunov function technique, two laws of switching between controllers are designed respectively, under which the systems are stable with H∞ disturbance attenuation. Moreover, two static state feedback H∞ control laws are given in terms of the solvability of two coupled linear matrix inequalities.
