摘　　要： 针对热轧带钢粗轧头尾宽度尺寸精度低的现状,分析了带钢头尾宽度超差的原因,提出了采用短行程控制(short stroke control,简称SSC)的解决方案。针对传统的短行程控制模型在实际应用过程中控制精度不高的问题,开发了短行程控制在线自学习功能。采用加法自学习的方法,利用轧后实测宽度数据对短行程控制模型参数进行自学习。国内某热轧厂现场实际应用表明:自学习后的短行程控制模型,能够将带钢头尾与稳定段宽度超差控制在2 mm之内;金属收得率提高到98%以上。 For the present situation of rough rolling strip head and tail low width precision on hot strip,the cause of strip head and tail width tolerance was analyzed,and the short stroke control（SSC for short） solving method was advanced.For low control precision of conventional short stroke control model in practice,the short stroke control online self-learning function was exploited.Through the method of addition self-learning,the self-learning of the short stroke control model parameters was realized using actual width data after rolling.The practical application at some domestic hot rolling mill show that short stroke control model after self-learning can control strip head and tail width and width of steady portion in two millimeters and metallic yield enhances to over ninety-eight percents.
