<p>PROBLEM TO BE SOLVED: To prevent the stability of a control by a delay occurring caused by a distance between shape detector and shape control mechanism, etc., from lowering, and to promptly correspond to the shape change of the rolling stock in the shape control of the rolling stock by a feedback control using the measured result of the shape detector. SOLUTION: In a method performing the shape control of the rolling stock by measuring continuously shape changes in the plate width direction of the rolling stock 1 by the shape detector 4 arranged on the outlet side of the rolling stand of the rolling line and by inputting the measured shape changes to the shape control mechanism of the rolling stand, while predicting the shape changes of the rolling stock, which are brought by the shape control mechanism by the output of a shape control signal before the shape changes of the rolling stock are measured by the shape detector 4 by a control model, the measured signals of the shape changes by the shape control mechanism are corrected according to its predicted results.</p> |
