摘要
用Matlab计算动态电路,可得到解析解和波形图。一阶电路先计算3要素,后合成解析结果;RLC串联和并联的二阶电路采用自编的通用函数计算,自编函数采用了Matlab求解微分方程的符号运算方法;一般的二阶电路和高阶电路采用拉氏变换列写电路方程,再用拉氏反变换得到解析结果。通过实例分析,展现了Matlab在动态电路分析方面的优越性。不仅使动态电路的计算变得简单,而且可得到解析的、可视化的结果。
Analytical solution and waveform can be got by using Matlab to calculate the dynamical circuit. Three elements should be calculated in first-order circuit, which can synthesise analytical solution. Second-order series RLC and parallel RLC both can be calculated by the general function , which uses the Matlab to calculate differential equations Generally, second-order and high-order circuits use Laplace transformation to formulate circuit equation, and get analytical solution by using Laplace inverse transform. The result shows the superiority of Matlab in dynamic circuit analysis. It can not only simplify the dynamic circuit calculation, but also get analytical and visualization results.
