摘　　要：KFF-AGC已在国内轧机投入应用,但效果不甚明显。为有效消除水印厚差、头尾厚跃和趋势性厚差,提出一种改进的KFF-AGC方案。该方案将所有厚差分为两类,采取不同的控制策略,并兼顾考虑降低偏心、系统延迟、高频随机波动的影响。经现场实验,该控制方案能大幅提高厚度控制精度。Though KFF AGC has been applied in domestic rolling mills,its advantages are not obvious.In order to get rid of skid mark deviation,head and tail thickness spring and tendency thickness deviation effectively,this paper put forward a sort of improved KFF AGC scheme.The scheme divides all thickness deviations into two groups,and adopts different control strategy,and at the same time gives attention to reduce the effect of eccentricity,time delay,and high-frequency random fluctuating.Experimentation with real situation has proved that the scheme can improve gauge control precision greatly.
