| 摘 要： | 为实现系统微分方程与系统框图的互换，介绍了“系统函数法”和“时域中间变量法”两种互换方法。分析表明：前者适合在给定系统微分方程的条件下画出串联或并联形式的系统框图；后者数学运算量小，操作简便，适合在给定系统框图的条件下，求取系统的微分方程。利用两种方法建立基于MATLAB／Simulink的模型，对高通滤波系统所作的仿真，证明了两种方法的正确性。

| Abstract: | The paper introduces the system function method and the time region new variable method, two exchange methods designed for system analysis and exchange between system differential equation and system chart. The comparison suggests that given system differential equation, the first method allows the production of a system chart in the series and parallel form and given system chart, the second one offers less calculation and an easier operation, hence a solution to system differential equation. The correctness of these two different methods is proved by developing models based on MATLAB/Simulink with the two methods in an effort to fulfil the simulation analysis of high pass filter systems. |
