摘　　要：在各个子系统均能检测且脉冲能观的条件下研究了切换线性广义系统的状态观测器设计问题.基于共同Lyapunov函数方法,给出了切换线性广义系统存在广义状态观测器和正常降维状态观测器的充分条件和设计算法.最后,以一个数值例子说明了该方法的有效性.The problem of design of observer for switched linear singular systems is studied under the conditions that all subsystems are detectable and impulse observable. Based on the approach of common Lyapunov function, a sufficient condition for the existence of singular observer and reduced-order observer is given; and the corresponding algorithm is also presented. Finally, a numerical example is given to illustrate the effectiveness of the proposed method.
