| 摘 要： | 在开环系统系数矩阵不含重特征值的情况下,本文揭示了分散控制系统中分散固定模与这一矩阵的各个特征向量之间的关系,从而提出了判别分散固定模的一种新方法.在此基础上,首次对分散状态反馈控制系统提出了在子系统间采用交义状态反馈控制以消除分散固定模的系统化方法及其原理,以及从避免产生分散固定模的角度来看决定最小反馈信息结构的方法.

| Abstract: | The relationship between fixed modes and eigenvectors of open-loop coe-fficient matrix with distinct eigenvalues in decentralized control systems is re-vealed in the paper.A new criterion of fixed modes based on the relationship is presented.The principle and systematic method of choosing cross state feedback control between subsystems to eliminate fixed modes in decentralized state feedback co-ntrol systems are proposed.A method for determining minimum state feedback information structure with the view of avoiding decentralized fixed modes is
also given. |
