板形控制中引入功效函数有助于更充分地发挥轧机的板形控制能力,改善带钢的板形质量.建立了基于功效函数的冷轧机板形控制模型,同时给出了相应的自学习模型,并将其应用到1450冷连轧机组的生产实践,所建立的功效系数模型及其自学习技术不但计算精度较高,能够满足工程需要而且计算过程非常稳定,计算速度能够得到保证,达到现场实际要求,取得了良好的使用效果,具有进一步推广应用的价值.
The concept of evaluation function is defined to describe the characteristics of shape contr01.The corresponding shape control model based on the evaluation function was given out and self-learning model was established and used on 1450 tandem mill.The model of evaluation coefficient and its self-learning are calculated accurately which can meet the engineering needs,the calculation process is very stable and the calculation speed can be assured.The model meets the actual needs of the field and gets good results,so the model can be popularized further.
