摘要
针对具有时滞性、多回路、强耦合等特点的锅炉加热过程中的温度耦合问题,设计了一种以主控计算机作为上位机,PLC作为控制器,PROFIBUS-DP和工业以太网为通讯方式的锅炉温度解耦控制系统。该系统采用模块化结构设计,可以对控制算法进行参数修改,从而使得温度控制系统更容易取得较为理想的解耦效果和动静态性能。基于Win CC的人机交互界面设计使得解耦系统操作简单方便,使学生能更直观地将理论知识与工程实践相结合,培养了学生的应用实践能力。
In order to solve the temperature coupling problem of boiler heating which has the characteristics in terms of time latency,multi-loop,and strong coupling,this paper designs a temperature decoupling control system,which consists of the master computer as the upper computer,the PLC as the controller,and the PROFIBUS-DP and the industrial Ethernet as the communication mode.This system adopts the modular structure design to modify the parameters of the control algorithm,accordingly,it becomes easier for the temperature control system to achieve better decoupling effect and dynamic and static performances.The WinCC-based human-computer interface makes the decoupling system easy to operate,combines the theoretical knowledge and engineering practice well,it can strengthen the ability of the application.
