多项式矩阵理论在网络分析中的应用

本文应用基本回路矩阵Ｂ、基本割集矩阵Ｑ和支路伏安特性矩阵［Ｙ（ｓ）Ｚ（ｓ）］列写出线性时不变有源网络的网络矩阵Ｐ（ｓ），借助于多项式矩阵理论中有关解耦零点的概念和理论，研究了网络的复杂度和稳定性。和文献［３］相比，不仅降低Ｐ（ｓ）阶次，减少了运算，且研究了复杂度。

Application of Polynomical Matrix Theory to Analysis of Linear Time-Invariant Active Networks

The order of complexity and stability of linear time-invariant active networks is studied by means of tha concept of decoupling zeros in polynomial metrix theory,and the network(or system)matrix P(s)is obtained hased on the fundamental loop metrix, fundamental cutset matrix and branch V-I relation matrix.Compared with Reference (3), the order of network matrix is lower,the elementary row operation becomes easier and the complexity is studied,too.
