基于MATLAB的过程控制系统课程仿真实验软件

Simulation Experimental Software of Process Control System Course Based on MATLAB

介绍在MATLkB语言环境下过程控制系统课程仿真实验软件的设计和实现,并用示例阐述其应用。过程控制系统课程仿真实验软件设计有两部分功能:根据用户输入的传递函数,实现对控制系统的建模,对其进行频率响应分析和时间信号响应分析,分析结果以曲线图形式反映出来;使用SIMULINK搭建4种典型系统用于系统仿真,通过对PID参数调节进行系统优化。软件的实现采用窗口和界面技术,充分利用MATLAB语言强大的功能和控制系统库函数。此软件主要应用于大学本科生过程控制系统课程的实验。

Under the MATLAB environment, design and implementation of simulation experimental .software of process control system course were introduced, and a demonstration of the software was expatiated. The function of the software is composed of two parts. One part is to model a process control system depending on input data, analyze its frequency response and time signal response, and the result is displayed in the form of a curve, The other part is to simulate four kinds of typical proceeds control systems by using SIMULINK, and optimize system by adjusting different PID parameters, Window and interface technology were used to implement the software. Many powerful functions of MATLAB were also fully employed, especially control system built - in functions. This software applies chiefly in the field of undergraduate course experiment of process control system.
