摘要
用MATLAB计算一阶、二阶动态电路和正弦稳态电路,不仅可以得到解析解,还可以得到波形图。一阶电路主要是先计算三要素,然后合成解析结果;二阶电路采用自编函数用MATLAB求解微分方程的方法;正弦稳态电路的向量图用MATLAB携带函数。用MATLAB包含的Simulink工具箱搭建仿真模型,可通过任意改变电路参数,得到不同的响应曲线,从而能够简单直观地理解电路的理论内容。通过实例分析显示了MATLAB在电路分析计算机辅助实验教学方面的优越性。
The analytic solution and the waveform of first order circuit,sencond order circuit and the sinusoidal steady-state circuit can be obtained by the MATLAB.In the first order circuit,the circuit＇s three basics were caculated first,and then syntesized the resolvable result;In the sencond circuit,the function was difined in the m-file,and the differential equation was solved by the MATLAB.The vector diagram of sinusoidal steady-state circuit made use of the MATLAB＇s function.The simulaiton model was established by using of the simulink tool,the parameter of the circuit was changed arbitrarily,and then the different response curve was gotten to understand the circuit theory simply and visually.The superiority of computer aided experiment teaching in the circuit analysis was developed by the examples based on MATLAB.
