厚板轧后加速冷却控制过程仿真系统

Simulation platform for accelerated cooling process of middle and heavy plate

该仿真系统以厚板轧后加速冷却控制系统为对象,创建了加速冷却整个控制过程闭环的仿真环境(包括过程控制系统L2、L1和冷却生产线模拟装置),实现了对冷却装置的预设定功能、前馈在线补偿控制功能、反馈自适应控制功能等。使整个离线系统完全仿真了目前在线生产中应用的过程控制系统的全部功能,为现场轧后冷却控制系统的精度提高、问题分析提供了研究分析的手段和平台,降低了新功能投入的风险。

For simulating the accelerated cooling process and its control system,a hardware-in-loop platform is established in this paper.The platform is designed including a pilot product line,the Level 1 and Level 2 control system.The control algorithms of presetting set points,feed-forward compensation control and adaptive feed-back control are realized in this platform,which makes the platform＇s control system have the same functions as the real product line owned.One can analyze the in-field problems and study how to improve the control accuracy through this platform in the first step,and then apply the results to the real product line.Therefore,the technical innovation risks are decreased dramatically.
