基于MATLAB-GUI的电机教学实验用控制系统的仿真平台

摘要

The simulation platform of the multi-func-tion control system was established based upon the simu-lative tool-box, Simulink of the MATLAB and visualiza-tion-programmable technology (GUI). The platform includ-ed motion control system, power electron technology and such auto-control theory commonly used in the teaching practice as speed-adjustable system of AC, DC and PM mo-tors, three-phase rectifier circuit and PWM inverting circuit as well as simulative modeling and analysis of the PID con-trol system, to perform the experiments which was hardly to perform by means of hardware before. It was helpful for the students to understand directly composition and principle of the commonly-used typical control systems.%以MATLAB软件的simulink仿真工具箱和可视化编程技术（GUI）为基，构建多功能控制系统的仿真技术平台。该平台包含运动控制系统、电力电子技术、自动控制原理实践教学中常见的直流电机调速系统、交流电机调速系统、永磁电机调速系统、三相整流电路、PWM逆变电路、PID控制系统的仿真模型和仿真分析，替代硬件实验无法完成的实验内容，有助于学生直观理解常见的几种典型控制系统的组成及工作原理。
