摘要: 讨论关联大系统分散回路传递再生的设计问题.利用矩阵的奇异值分解技术,提出了对 关联项进行块对角化处理的一种新方法.基于H∞理论,将多变量系统的回路传递再生方法 推广于分散控制关联大系统,并避免了在所有可能的分散观测器增益构成的集合上,直接计算 再生矩阵的H∞范数下确界的困难.Abstract: In this paper, the design problem related to the decentralized loop transfer recovery for large-scale interconnected systems is discussed. It develops a new method which makes interconnections between subsystems be "block-diag" by using matrix singular value decomposition technique. The LTR of centralized multivariable control systems is then generalized to decentralized control large-scale interconnected systems by H∞ optimal theory. The difficulty to compute the infimum of H∞-norms of recovery matrices in the set of all possible gains of decentralized observers is avoided.
