Abstract: To provide a shape control device of a cluster rolling mill that is capable of stably controlling a shape, even when a local shape defect has arisen.SOLUTION: A shape control device includes: a shape deviation calculator; a regularization parameter change section; and an operation amount calculator. The shape deviation calculator calculates a shape deviation which is a difference between an actual shape of a rolled material measured by a shape meter, and a target shape of the rolled material. In a case that a value related to a shape defect in a width direction of the rolled material is larger than a threshold, the regularization parameter change section changes a regularization parameter for adjusting an influence degree of a regularization term to a value that is greater than a value in a case of the threshold or less. The operation amount calculator calculates an operation amount of the actuator for shape controlling, that minimizes an evaluation function of the shape deviation into which the regularization term containing the regularization parameter is introduced.SELECTED DRAWING: Figure 1
