摘要
计算机控制系统相关课程对硬件的需求较高,极大地增加了实验成本。传统的单纯数字仿真难以提供生动形象的实验过程,阻碍了课程教学效率。为了解决问题,对计算机控制系统仿真实验平台进行了研究,完成了基于Simscape仿真实验平台的设计,模拟迭代计算差分方程的过程,通过物理模型模块完成被控电路系统的构建,结合使用触发子系统及相应程序进行计算机系统仿真,实现对计算机周期性采样过程的模拟。以二阶电路系统的最少拍控制为例对仿真设计过程进行阐述,为搭建相关课程的仿真实验平台提供参考。
The computer control system related courses have higher requirements on hardware, which greatly increases the experimental cost. The traditional simple digital simulation is difficult to provide a vivid experimental process, which hinders the efficiency of the course teaching. In order to solve the problem, a system simulation experiment platform was studied. The design of the simulation platform based on Simscape was completed. The process of iteratively calculating the difference equation was simulated. The construction of the controlled circuit system was completed by the physical model module. The system was simulated by using the trigger subsystem and the corresponding program. The simulation of the computer periodic sampling process is realized. The simulation platform is explained by taking the minimum beat control of the second-order circuit system as an example to provide a reference for the simulation experiment platform of the relevant course.
