由信号流图建立状态方程的系统方法

Systemetic Method of Establishing State Equation by Signal-Flow Graph

本文给出了一种新的建立电路状态方程的方法，文中把信号流图简化为一种状态矩阵流图，并导出了矩阵流图中各传输矩阵的计算公式，由此很容易写出状态方程。

A new method for establishing the state equation of circuit is given in this paper in which the signal-flow graph is simplified as a state matrix flow graph, and all the calculation formulue for the transmission matrix are deduced, so it is easy to obtain the state equation.
