摘　　要：传统的自动原理实验课需要配置相关实验箱,就会存在实验器材更新换代慢,维修频率高,维护费用高等问题。鉴于这中情况,提出了利用MATLAB软件建立自动控制原理实验课程的仿真实验平台。采用SIMLINK和相关函数实现信号的模拟及绘制响应曲线。研究了随相关参数的改变系统的响应也随之改变,任意系统根轨迹的描绘等实验内容。经实验证明基于MATLAB的虚拟仿真实验平台的实验效果良好,完全可以满足实验要求。The traditional automatic principle experiment class needs to configure the related experiment box, There will be the problem that experimental equipment replacement had been slow, the frequency and costs of Maintenance had been high. In view of this situation, the paper propose that there will set up the simulation experiment platform of automatic control principle experiment course.Realize signal simulation and draw response curve by Simlink and correlation function. Research the response of the system changing with the related parameters changing, and the root locus of any system descripting.The experimental results show that the virtual simulation platform based on MATLAB has a good effect, and can meet the requirements of the experiment.
