针对一类具有状态及控制滞后的不确定系统,研究了其鲁棒H_∞控制,用线性矩阵不等式的方法设计了一种状态反馈控制器.该控制器在鲁棒镇定系统的同时,能保证闭环系统从扰动到被控输出的H∞范数小于某一给定的常数.
For a class of uncertain systems with state and control lag, a robust H_∞control is studied and a state feedback controller is designed by using the method of linear matrix inequalities. The controller can guarantee robust stabilization of the system, The H∞ norm of the closed-loop system from disturbance to controlled output is less than a given constant.
