中厚板轧制力自学习过程层别跳变的自整定方法

在中厚板轧制力预报过程中,为防止自学习系数沿着厚度层别发生跳变,提出了中厚板轧制力自学习过程层别跳变的自整定方法.针对厚度层别表中的每一个厚度节点计算其半宽带,然后根据半宽带计算厚度节点的有效区域,最后找到当前轧制厚度的有效区域并确定它所对应厚度节点的权值,从而得出自整定后的自学习系数.实际应用结果表明,应用该方法后轧...

Self-adjusting for Plate Thickness Layer Skipping in Rolling Force Learning Process

In the prediction process of rolling force for plates,to prevent the self-learning coefficient from the skipping along thickness layers,a self-adjusting method was put forward in the self-learning process of the rolling force for medium/thick plates.In the method the half-width zone was calculated according to every thickness node as listed in the table of thickness layers,then the range of validity of a thickness node was calculated according to half-width zone so as to find out the validating range of the...
