Title:
蛇行制御システム、蛇行制御方法、およびプログラム
Document Type and Number:
Japanese Patent JP7131235
Kind Code:
B2
Abstract:
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
