A control apparatus (10) for controlling a die cushion mechanism (12) including a servo-motor (14) as a drive source and producing a force adapted to be applied outside. The control apparatus includes a force commanding section (18) for commanding a force to be produced by the die cushion mechanism; a force detecting section (20) for detecting a force produced by the die cushion mechanism; a force controlling section (22) for executing a force control on the servo-motor, based on a force command value (C1) commanded by the force commanding section and a force detected value (D1) detected by the force detecting section; and an abnormality preventing section (24) for preventing, in association with a control state of the servo-motor, the die cushion mechanism from producing an abnormal force (F).
