ABSTRACT:
A motor control device comprises: a current limiter115for limiting a current-instruction signal Ir for a motor18and for turning a limiting signal L from off to on when the current-instruction signal Ir reaches a predetermined value; a model-position-generating part220having a model of an equivalent position-control system that includes characteristics of the motor control device100and a control target object, and calculating rotational position of the motor18as a model-position signal θm by inputting to the model a position-instruction signal θr; a correctional acceleration-generating part240for generating a correctional acceleration signal αse based on a correctional position deviation θse when the limiting signal L turns on; and a position-instruction-generating part260for generating the position-instruction signal θr based on an acceleration deviation αr that is equal to the difference between the original-acceleration-instruction signal Va and the correctional acceleration signal αse.
