Abstract
A control device controls a generation force of a force generating mechanism including a permanent magnet and an armature that generate an adjustable force between a first member and a second member. The control device includes: a command value acquisition unit that acquires a generation force command value of the force generating mechanism; a relative displacement acquisition unit that acquires a relative displacement of the permanent magnet and the armature; a movement direction command acquisition unit that acquires a movement direction command of the armature with respect to the permanent magnet from the generation force command value; and an actual movement direction acquisition unit that acquires an actual movement direction of the armature with respect to the permanent magnet from the relative displacement. The generation force command value is corrected by acquiring a correction value based on the movement direction command and the actual movement direction.
