本文利用(A、B)特征子空间来讨论分散控制中局部反馈的作用。这里主要讨论两个控制站(两通道)的情况,给出局部反馈u_2=K_2y_2使B_1不能控部分循环指数最小的数值,提出在B_1端增加输入信号来达到单通道能控的方案。文章还证明了利用局部反馈u_2=K_2y_2使(A+B_2K_2C_2,B_1)成为能控对的条件。这些条件用特征子空间来描述是十分简洁的。最后还利用(A、B)特征子空间刻划了分散固定模的一个本质的特征。
This paper uses (A, B) feature subspace to discuss the role of local feedback in decentralized control. We mainly discuss the case of two control stations (two channels), and give the value of partial feedback u_2 = K_2y_2 to make B_1 uncontrollable the partial cyclic index. We propose to increase the input signal at the B_1 end to achieve the single-channel controllable scheme. The article also proves that using the local feedback u_2 = K_2y_2, (A + B_2K_2C_2, B_1) becomes the condition of controllable pair. It is very succinct to describe these conditions in terms of subspaces. Finally, we use (A, B) subspaces to characterize an essential feature of decentralized modules.
