摘要: 本文首先讨论了最经济分散信息结构解的存在性问题,然后给出一个适用于任意反馈结 构限制并能确定固定模代数重数的判据.这个判据确定了任意单个反馈元及其组合对移动开 环极点的贡献,从而提供了综合最经济分散信息结构所必须的基础信息.在此基础上,作者提 出递推型的最经济信息结构综合算法以及在此结构下分散控制系统的设计过程,并以具体算 例作了说明.Abstract: In this paper, the existence of the solution for the Most Economical Information Structure (MEIS) problem is discussed. A criterion for determining the fixed modes as well as their multiplicities, applicable to arbitrarily restricted feedback structure, is then given. This criterion provides the possibility to evaluate the contributions of all single feedback elements and their combinations to the removing of the open-loop poles and thus furnishes the necessary information for synthesizing the MEIS. On this basis, the authors present a recursive algorithm for synthesizing MEIS and propose the design procedure of decentralized control systems with the MEIS. Finally, a numerical example is given for illustration.
