微型锅炉液位模糊PID控制

Fuzzy-PID Control of Micro-size Boiler's Level

本文研究基于Profibus现场总线和以太网两级网络的过程控制系统实验装置,被控对象是模拟电热锅炉。重点介绍了模糊PID控制算法在锅炉液位控制实验系统中的应用,说明了实验原理和实验教学应用软件设计开发过程。实验结果表明,在Fuzzy-PID控制下,系统的动、静态性能均优于传统的PID控制器。

A process control system based on two-level networks--Profibus and Ethernet for experimental equipment is studied in this paper. The controlled object is a process imitating the electrothermal boiler. The application of fuzzy-PID control to the boiler＇s level control experiment is emphasized by exhibiting the experiment principle, the design and development process of the experimental teaching application software. The field test shows that with Fuzzy-PID control the system＇s dynamic and stationary performances are better than with classical PID control.
