基于模糊控制的的总线型温度监控系统的设计

Design of the temperature monitoring system based on fuzzy control and fieldbus

温度是工业生产中的重要参数,温度控制对生产起着至关重要的作用。文章应用了模糊控制算法及现场总线等技术,设计了一种实时温度监控系统,介绍了该监控系统的工作原理及软硬件设计,在结构上分为上位机监控单元和现场控制单元,在温度的控制方面设计了一种由软件实现的模糊PID控制器,上位机与现场控制单元采用CAN总线进行通信。

Temperature is an important parameter in industrial production and temperature control plays a vital role in the production.This paper designs a real-time temperature monitoring system which applies the fuzzy control algorithm and fieldbus technology.The paper describes the working principle of the presented monitoring system and the design of software and hardware.The system is composed of the host computer unit and the on-site control unit,and the host computer communicates with the on-site control unit through CAN bus.A fuzzy PID controller implemented by software is designed for temperature control.
