摘　　要：在板带轧制厚度控制过程中,在辊缝位置闭环控制模式下,可通过检测轧制力的变化来修正辊缝目标值,使出口厚度与目标厚度保持一致。用递推法推导出了压力正反馈厚度控制的动态模型,并证明了其收敛性。The rolling force can be acquired in gap cloee - loop control of aluminum plate mill. It can modify the gap to keep the exit gauge following the aim. The dynamic model of force positive feedback has been set up through formula ratiocination. Its convergence has been proved.
