摘　　要：对板形计法 (板形测控数学模型 ,解析板形刚度理论和板形板厚协调规律 )的计算公式进行了推导 ,得出了更为简明的计算公式 ,并得到基本模型的三参数 (柔性系数 ,干扰系数和轧辊实时凸度 )的自适应方法。板形板厚目标的统一 ,DAGC实现板形板厚最优控制等 ,推进了最优控制理论在轧制过程的工业应用进程。After calculation of algorithmic formula for flatness-meter method used in flatness measure-control model, flatness stiffness solving theory and association with strip thickness, a simplified formula is present. And also gives adaptive feedback way of three model parameters, e.g. flexibility coefficient, disturbing coefficient and real-time roll crown. In order to unify flatness and thickness control, DAGC will performs optimizing flatness control associated with thickness, and result in progressive forward of rolling process in optimizing control theory.
