基于RTWT的自动控制原理实验设计与实现

Design and realization of Automatic Control Theory experiment based on RTWT

针对现有的EL-AT-Ⅲ自动控制实验箱扩展性不好、实验内容陈旧、难以实现高阶系统和复杂控制算法实验的缺点,开发了基于Simulink/RTWT的半实物仿真实验系统。实物部分采用实验箱的运放、电阻、电容搭建实验电路,或接入锅炉、水箱等实物对象,仿真部分通过Simulink搭建控制框图,RTWT保证程序实时运行。该实验系统具有开放性,有助于培养学生的工程意识和设计系统、调试系统的能力。

Aiming at the drawbacks of the existing Automatic Control Theory experiment, such as no extending space,out-dated contents,difficult to achieve high order system,modern control theory and complex control algorithm,a semi-physical simulation experimental system based on Simulink/ RTWT is proposed. Physical parts adopt experiment box,boiler, water tank and so on. Simulation parts build Simulink model. The RTWT guarantee program runs in real time. Practice shows that the system can not only make up the defects of the experimental box, but also improve students＇ enthusiasm, cultivate their engineering consciousness, develop their ability to design and debug systerms with its open platform.
