摘　　要：研究一类切换广义系统的观测器设计问题。首先设计第i个子系统的子观测器,然后当第i个子系统被激活时,可以通过采用第i个子观测器构造这个广义切换系统的观测器。当观测器是全维观测器,且每个子系统都可检测时,如果驻留时间足够长,那么状态估计误差能够收敛到零。在某种条件下,状态估计误差甚至可以在任意切换下指数收敛到零。The observer designing for a type of switched linear singular systems was discussed.Firstly,the sub-observer of the No.i sub-systems was designed,then when the No.i sub-systems was activated,the observer of switched singular systems can be formed by using the No.i sub-observer.If lingering time of full-dimensional observer whose each sub-system is checked is enough,state estimate error can converge to zero.In some case,state estimate error converge to zero by exponent under any switching.
