不定割集导纳矩阵及其应用

Indefinite Cutset Admittance Matrix and Its Application

提出了双树支割集和不定割集导纳矩阵的概念，讨论了它们的性质及不定割集导纳矩阵的直观编写方法，并将其应用于求网络函数和反馈放大器系统的回归差、零回归差及灵敏度等方面．结果表明不定割集导纳矩阵是不定节点导纳矩阵的广义化概念．

Based on double tree branch cutset, indefinite cutset admittance matrix and its application network are presented. It is shown that the indefinite cutset admittance matrix is a generalized concept of indefinite node admittance matrix. Various network functions, the return difference, the null return difference and the sensitivity with indefinite cutset admittance matrix could be calculated. These formulations are convenient to networks excited by voltage sources, or containing current controlled voltage sources and coupled inductors, as compared to the formulations with the indefinite node admittance matrix. This significance of the new formulation is of universal.
