摘　　要：讨论了一类组合系统的变结构鲁棒观测器的设计及这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 。The problem of robust observation synthesis and decentralized stabilization for large- scale systems subjected to nonlinear interactions and bounded uncertainties is considered.The scheme of the variable-structure-observer is proposed and the observation error is guaranteed to converge asymptotically to zero,and by using the estimated states feedback,the decentralized control law is obtained which guarantees that the closed-loop systems to be asymptotically stable.
