Abstract:  

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.

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。
