摘要
为了解决自动控制原理课程单纯硬件实验存在的成本高、效率低等问题,提出了一种虚拟实验平台开发方案。利用Matlab/Simscape软件提供的相应组件搭建了针对各个实验内容的实验子系统,详细地阐述了这些子系统的实现过程。最后以二阶系统的单位阶跃响应分析和频率响应特性曲线绘制为例具体介绍了实验子系统的使用方法,并用自动控制理论分析了仿真实验平台运行的准确性。结果表明,作为硬件实验前的有效补充,在虚拟实验平台上的仿真实验过程和实际硬件实验过程一致,可极大激发学生的实验兴趣,提高实验效率。
Abstract：In order to solve the problems of high cost and low efficiency in students experiments at the actual platform for the course of Automatic Control Theory,a new kind of automatic control theory virtual experiment system is proposed in this paper.Using relevant modules provided by the software of Matlab/Simscape,a platform for most experiments of Automatic Control Theory are built.Taking the analysis of the response to a unit step and the frequency response of second-order system as examples,the design course of the experimental platform and the using method are illuminated in details.Furthermore,the accuracy of the running result from the platform is analyzed using control theory.The results show that the simulation experimental process at the platform is very similar to the actual process,and with the help of the virtual experiment,the interest of students and the experiment efficiency will be improved largely.
