To shorten a time until an observer estimate is set and to achieve high-response meandering control of a plate rolled material.SOLUTION: A leveling amount calculator 200 has: a pseudo-differentiation part 202 which derives a value in which a measured value of a plate rolled material 5 measured by a meandering meter 20 is pseudo-differentiated as a calculated value of a time differential value of a meandering amount of the plate rolled material 5 at a rolling mill position; and leveling operation amount derivation part 204 which derives a levelling operation amount of a rolling mill 2 by use of the calculated value of the time differential value of the meandering amount of the plate rolled material 5 at the rolling mill position which has been derived by the pseudo-differentiation part 202.SELECTED DRAWING: Figure 2 【課題】 オブザーバの推定値が整定するまでの時間を短縮し、板圧延材の蛇行制御を高応答にする。【解決手段】 レベリング量演算器２００は、蛇行計２０により測定された板圧延材５の蛇行量の測定値を擬似微分した値を、圧延機位置における板圧延材５の蛇行量の時間微分値の計算値として導出する擬似微分部２０２と、擬似微分部２０２により導出された圧延機位置における板圧延材の蛇行量５の時間微分値の計算値を用いて、圧延機２のレベリング操作量を導出するレベリング操作量導出部２０４と、を有する。【選択図】 図２
