基于观测器的不确定动态时滞系统鲁棒镇定的Riccati方程方法

本文给出了一类不确定动态时滞系统基于观测器的鲁棒镇定方法，该类系统的状态、输人和输出矩阵均含有不确定性，且不确定性需满足给定的匹配条件，系统不仅有状态时滞，还有控制时滞，该方法通过求解两个代数Riccati方程实现，本文比较全面地解决了满足匹配条件的不确定动态时滞系统的鲁棒镇定问题．

An Observer-Based Riccati Equatuon Approach for Robust Stabilization of Time-Varying Delayed Uncertain Systems

In this note,we present a robust stabilization method for a class of observer-based time-delayuncertain systems where the uncertainty satisfies the matching conditions. These systems have delays in bothstate and control input. Through solving a pair of Riccati equations,observer-based feedback controller is obtained. The paper completely solves the robust stabilization problem of systems where the uncertainty satisfies the matching conditions.
