摘要
反应釜是一种典型的大惯性、滞后性系统,控制起来非常困难。以反应温度作为被控参数,采用上、下位机结合的整体方案和动态PID温度控制算法。介绍了基于VB6.0的上位机监控界面开发和基于C8051F020单片机的下位机控制器的设计,包括控制器软硬件设计、上下位机串口通讯、数据存取与实时数据显示等。并应用到实验室反应釜进行温度控制,结果验证了软硬件设计和控制算法的可行性和有效性。
Taking the temperature of inner reactor as mainly controlled parameter,the control system combines the PC and the MCU,using dynamic PID control algorithm was designed.The development of HMI based on VB6.0 and the design of regulator based on C8051F020 MCU were introduced,including hardware structure of regulator,software design,serial communication,data access,dynamic data-graph display and so on.The experiment on the reactor in lab shows that the design of software,hardware and control algorithm are feasible and effective.
