摘　　要：针对网带式电阻炉的非线性、大滞后、参数时变等特点,基于Active-X技术提出了生产指标优化的电阻炉温度控制系统。系统硬件采用PC机、热电偶、研华ADAM模块、可控硅等,使用组态王做用户监控界面,控制算法采用改进型分区积分PID,应用Active-X技术将控制算法用VB编写并生成Active-X控件。所提出的系统成功应用于某厂电阻炉生产过程,现场应用表明该温度控制系统的控制精度优于±2°,同时具有稳定性高,操作方便等特点,控制品质符合工艺要求,产品质量得到明显提高。To the web-strip hot furnace characters such as nonlinearity, large time delay, varying parameters, a temperature control system is presented based on Active-X. The hardware contains industrial computer, thermocouples, ADAM modules, silicon controlled rectifier etc. User monitoring contact surface is written in Kingview. The control algorithm uses advanced version district integral PID and compiled by VB using the Active-X technology. The proposed system is successfully applied to the thermal process of a factroy. The application restdt shows the higher stability and lower power consumption. The controll precision reached ± 2 °, and the product quality has the distinst improvement.
