Abstract

Control is kept at a certain extent while the objective different from the original objective is achieved. For a controlled object, if a plurality of control systems are adopted, the control target value of each control system is varied so as to obtain a control target. The control target value of the plurality of control systems is varied within the allowable value of the control accuracy, and the objective different from the original objective is achieved by generation of interference between the control systems. For shape control of a rolling apparatus, it is possible to control the end section of a plate by varying the target shape of bender control and coolant control.
