摘要
基于Ｈ∞理论和分散状态观测器，提出了不确定性关联大系统的分散开环回路传递再生方法．给出了满足开环再生矩阵Ｈ∞范数要求的观测器的存在性．在大系统关联项块对角奇异值分解的基础上，证明了通过解Ｒｉｃｃａｔｉ方程可以求得使开环再生差阵满足要求的分散观测器增益阵，以实现分散开环传递再生．试验结果表明，分散开环回路传递再生控制性能与分散状态反馈控制性能基本相同．
A method of decentralized open-loop transfer recovery is proposed for uncertainly interconnected large-scale systems, which is based on the H∞ theory and decentralized state observers. The existence of those observers which satisfies the requirement for the recovery matrix H∞-norm, is given. Based on the block-diagnal singular value decomposition to the interconnections of the large-scale systems, we proved that the decentralized observer gain matrix can be obtained by solving Riccati equations, and open-loop recovery difference matrix satisfies the requirement.The decentralized open-loop transfer recovery is then realized. The experiment results show that the control performance of the decentralized open-loop transfer recovery are similar to that of the decentralized state feedback.
