本文运用 Grassmann 代数和 Coates 流图对单输入-单输出闭环系统的极点配置提出了一种新方法,并论证了一个定理,即 M 方阵行列式的分子多项式是该闭环系统的特征方程. In this paper, we propose a new method for the pole placement of a single-input-single-output closed-loop system using the Grassmann algebra and the Coates flow graph, and demonstrate a theorem that the molecular polynomial of the M square matrix determinant is the characteristic equation of the closed-loop system.
