Matlab语言与线性电路的符号仿真

Matlab Language and Symbolic Simulation for Linear Circuit

目前的电路仿真软件通常是在电路中所有元件值都是给定的情况下得到一些数值结果 ,而非解析结果。该文利用Matlab的符号运算功能编程 ,通过节点列表法 ,实现了任意线性电路的自动解析求解 ,为电路分析提供了一个有效的辅助工具。

The present software for circuit simulation normally works at the con dition that all the parameters of the circuit components have assigned values, a nd only numerical other than analytical result is obtained. We make use of the M atlab function of symbol operation, and write a Matlab program by node table met hod. It can solve any linear circuit automatically and analytically. So analytic al result can be obtained. It would be a helpful and efficient tool to circuit a nalysis.
