摘要： A control device (10) for a die cushion mechanism (50), for carrying out force control with high accuracy and at a high speed. The control device for controlling the force generated by the die cushion mechanism utilizes a press working cycle which is repeatedly carried out. A correcting part (203) of the control device corrects each deviation in one working cycle based on a time-series of deviation data in the just before press working cycle. By repeating this operation, the deviation between the detected value and the commanded value may be converged toward zero. Therefore, the deviation may become smaller than that of the conventional feedback control, whereby it is possible to respond to a change in the commanded value in a short time.
