高阶动态电路数值解法

用手工求解描述高阶动态电路的微分方程初值问题几乎是不可能的。在MATLAB环境中编程运行可以快速给出高阶动态电路的时域数值解,必要时物理建模和数据拟合还可以得到解析解。高阶动态电路问题的MATLAB程序解法,通用性强,程序设计简单,对电路阶数和信号源几乎无限制。实例展示列写高阶动态电路状态方程的技巧,编写MATLAB程序给出状态方程数值解及可视化输出的关键思路。

The numerical solution of high order dynamic circuit

Abstract: To manually calculate differential equation initial value problems of higher order dynamic circuit is almost impossible. Programming running in the MATLAB environment can quickly give the time-domain numerical solution of high order dynamic circuit, if necessary, physical modeling and data fitting can also give analytic results. The method of high order dynamic circuit problem by MATLAB program have universality and simple program design, it almost have no restriction on the circuit order or the signal source. The example shows the writing skills of high order circuit equations and the critical ideas of writing a MATLAB program to give the numerical solution of the equation and the visualization output.
