冷轧板形反馈控制系统中，对工作辊的乳化液分段冷却控制至关重要。为此，考虑板形在空间和时间上的变化，采用绝对板形偏差、在时间上波动的板形偏差和在空间上波动的板形偏差三部分偏差，设计了乳化液分段冷却模糊控制算法，计算出板形缺陷严重程度的隶属度值，并依此来确定乳化液分段冷却喷嘴的开闭状态。该方法能够更好地减小高次板形缺陷和残余板形误差。

The control of emulsion subsection cooling for the work roll in the closed-loop feedback control system of cold-rolled strip flatness is crucial. A fuzzy control algorithm is designed based on the values of the absolute flatness deviation and the spatial and temporal variations of the flatness de-viation. It can use them to calculate the membership grade values which can describe the shape defect degree,and thus to determine the switch states of the emulsion subsection cooling nozzles. The control of emulsion subsection cooling for the work roll using the fuzzy control algorithm can better decrease the higher and residual flatness defects.
