摘　　要：由于变刚度压力厚度自动控制系统(BISRA AGC)对于轧机内部干扰引起的带钢厚度偏差不仅不能消除,而且还对其有放大作用,因此唐钢冷轧薄板厂1650mm可逆式冷轧机采用了以BISRA AGC为主、测厚仪反馈为辅的厚度闭环AGC控制系统,研究了厚度闭环AGC系统的主要问题——调节器参数的自适应控制.结果表明控制效果良好,产品厚度偏差控制在±5μm以内.BISRA AGC is said variable stiffness pressure gauge control system. It is deduced that BISRA AGC doesn＇t dispel itself disturb from strip mill cause of thickness deviation, but also blow up it. Therefore the loop AGC is appilied in 1 650 mm Reversing Cold Strip Mill of Tangshan Iron and Steel Company. The main problem of gauge closed loop AGC system is adaptive problem of adjuster parameters control. The practical effect is obviously good. The gauge deviation is controlled in ±5 μm.
