Abstract
In a configuration control system of product material in a strip rolling, to recognize a configuration pattern of a strip material, to clarify the correspondence between control actuators 10, 11 and 12 and configuration defect pattern and to separate local defects, a configuration pattern detected by a configuration detector is converted by an orthogonal function expansion operation device 3 to a series of orthogonal functions, specifically of polynomials, and operation amounts of the respective control actuators 10, 11 and 12 are controlled by coefficients of the respective functions.
