摘　　要：本文研究了一类具有圆盘极点约束的不确定线性切换系统的鲁棒镇定问题.对此类系统设计了状态反馈控制器,使得闭环系统的所有极点均位于一个给定的圆盘中,并得到了一个基于LMI的充分条件.通过求解线性矩阵不等式,可以构造一个具有较小反馈增益参数的状态反馈控制器.最后的仿真算例证明了本文结果的有效性。The robust stabilization for uncertain linear switched systems with disk polo constraints is studied in this paper,. State feedback controller is designed so that the poles of the closed-loop system can be assigned in a prespecified disL A sufficient condition based on LMI is therefore obtained. The problem of designing the controllers with smaller gain parameters is solved based on LMI conditions. The simulation shows the validity of the results .
