PID控制系统交互式虚拟仿真软件的设计

Designation of interactive virtual simulation software for PID control

介绍一种用于学习PID控制系统的交互式虚拟仿真软件及其设计方法,该软件可用于"自动控制原理"、"过程控制"等课程的辅助教学、虚拟实验以及学生的自学。仿真软件基于V isual C++、M atlab/S imu-link、和M atlab/RTW设计开发,实现了PID控制器设计、PID控制器参数整定等相关内容的多种仿真实验,帮助学生更直观地理解PID控制的物理意义和工作原理,培养了学生的研究能力和综合应用能力。

This paper describes a kind of interactive learning software of PID control and it＇s design method.This software can be used for assistant teaching,virtual experiment,self-study in teaching ＂The principle of automatic control＂ and ＂Process control＂ etc.The development of this virtual simulation software is based on Visual C＋＋,Matlab/simulink and Matlab/RTW.By using it,many kinds of simulation experiment about PID control can be done.It help students to directly comprehend the physical meaning and working principle of PID control,and trains students＇ ability of research and synthetically application.
