摘要

PROBLEM TO BE SOLVED: To optimally control a meandering amount of a rolled material on-line without requiring much cost and labor.SOLUTION: In meandering control processing being one embodiment of the present invention, an observer 100a detects a rolling difference load Pvia a rolling difference load detection part 102, and calculates estimate values of a meandering amount wand an input side angleθby using the detected rolling difference load P. A meandering control controller 100b operates a leveling amount Son the basis of the estimate values of the meandering amount wand the input side angleθand an integral valueωof the meandering amount w. Thus, the meandering amount of the rolled material can be optimally controlled on-line without requiring much cost and labor.
