摘　　要：分析了唐山钢铁集团有限责任公司1650mm可逆冷带轧机厚度控制系统中的BISRA AGC改进模型及其对由轧辊偏心等轧机内部干扰引起的带钢厚度偏差的消除能力。该模型不仅不能消除此厚差,反而是原来的1+Q/M倍,为此采用了以压力AGC为主、测厚仪反馈为辅的厚度闭环AGC控制系统,并取得很好效果。The ability of BISRA AGC model to eliminate the gauge deviation of strip and the causes of bringing out the gauge deviation of strip, such as roll eccentricity, etc., of 1650mm reversing cold mill of Tanggang were analyzed.The gauge deviation of strip can be enlarged to （1 ＋ Q/M） times of the original one by the BISRA AGC model. Therefore, the loop AGC system was applied, and the good effects were obtained.
