ABSTRACT:
An improved plate flatness control method adapted to effect a control so that plate flatness of a rolled material is made optimum by adjusting manipulated variables. In determining correction quantities of the manipulated variables, under the constraint that upper and lower limits exist in at least one of the manipulated variables and the correction quantities, a weighted square sum of deviations of a plate flatness distribution in the width direction of the rolled material is taken as an objective function to determine, using a non-linear programming, correction quantities of the manipulated variables where the objective function becomes minimum, thus, to control the plate flatness of the rolled material on the basis of the determined correction quantities of the manipulated variables.
