Abstract
A method of controlling a form of a strip in a rolling mill. A plurality of paired data of manipulation amounts of form control actuators, and amounts of variations in the form of the strip corresponding to the manipulation amounts are prepared, as prototype manipulation examples. Calculation is performed to obtain a degree of similarity between an actual form error representing difference between an actual form of the strip and a target form, and variations in the form of the prototype manipulation examples. Then, actuator manipulation amounts of the prototype manipulation examples are weighted in accordance with calculated degree of the similarity, and the actuators are manipulated based on weighted actuator manipulation amounts.
