讨论一类组合系统的鲁棒观测器的设计及该类系统基于估计状态反馈分散镇定问题。所设计的变结构观测器使得观测误差渐近趋于零 ,基于估计状态所设计的鲁棒分散控制器确保闭环系统是渐近稳定的 ,系统的相似结构使得所设计的各个子系统的分散观测器以及控制器在结构上具有一致性 ,从而简化了系统的设计。 This paper discusses the design of robust observers for a class of combinatorial systems and the decentralized stabilization of such systems based on estimated state feedback. The designed variable structure observer makes the observation error approach to zero asymptotically. The robust decentralized controller based on the estimated state ensures that the closed-loop system is asymptotically stable, and the similar structure of the system makes the scattered observation of each subsystem designed The structural consistency of the controller and controller simplifies system design.
