摘要
热轧卷取温度控制的数学模型研究的已经比较成熟,而对整个热轧卷取温度控制系统的综合开发与应用却不够。本文给出卷取温度控制系统的结构,提出采用动态修正预设定模型、头部自学习修正模型参数、全长监控来改善控制质量的控制思想并给出相应控制算法,将其应用于莱钢1500mm带钢热连轧机组,实践证明该控制系统运行稳定,控制精度高,很好地满足用户的要求。
The mathematic model of coiling temperature control （CTC） in hot strip rolling were well researched, while the development and application of the whole system is poor. This paper provides the structure of the CTC control system; brings forward that to correct the presetting model dynamically, to modify model parameters by strip head self learning and to improve the quality by whole-long feedback control and also gives the arithmetic of control. It has been proved by practice that the whole system was steady and the control precision was good. It is satisfaction for the users.
