Abstract: PURPOSE:To remarkably reduce the variation of plate thickness and to perform cold rolling excellent in yield by estimating the variation of plate thickness on the inlet side in accordance with the variation of rolling pressure at a preceding stand and converting its estimate into a disturbance. CONSTITUTION:A deviation  P of rolling force at the preceding stand is divided by a mill constant M to estimate a disturbance hi of plate thickness at the inlet side of the stand.  hi multiplied by a plate thickness ratio ho/hi and an influence coefficient K is converted by a plate thickness meter 5 into a variation  ho of plate thickness. ho is subtracted further from the difference between a measured value ho by a plate thickness meter 5 and a calculated value by a model to require a deviation by an error of a mode Gp'. Learning calculation is performed by a learning calculation part 22 in accordance with the deviation of the calculated value to change the Gp' dynamically. In this way, the control system Gp' is approached to the actual transfer function Gp of the rolling mill. Consequently, a high-precision Smith compensation method can be realized to restrain the compensation for the dead time and the influence by a disturbance.
