摘　　要：对一类子系统为线性的开关切换系统进行观测器设计 ,并给出系统动态输出反馈可镇定的充分条件。在所设计的观测器基础上 ,以系统状态的观测值为依据设计各子控制器和切换方案 ,使整个闭环系统是指数渐近稳定的。对于切换时间间隔受限制的情况 ,给出了相应的动态输出反馈可镇定条件和镇定控制方案。实例仿真结果表明 ,所给出的设计方案是可行的。An observer is designed for a class of switching systems whose sub-systems are linear. A sufficient condition for the stabilization of the system by dynamics output feedback controller is also presented. Based on designing the observer, a switching strategy and sub-controller, which use the observer value, are designed to guarantee that the closed-loop system is exponentially asymptotically stable. When the switching interval time is constrained, control scheme and stability condition for dynamic output feedback control are given. Finally, an example is given to show the feasibility of the given strategies.
