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.Abstract: 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.
