ABSTRACT:
An accurate load position control is made possible even when rigidity of a load drive system using a motor is relatively low. Load position signal xlis a present-position measurement value of a load, and after compensation in response to a phase delay thereof has been performed by a stability compensation circuit, the high-frequency portion thereof is taken as a control-target position signal xfbby replacing, in a position-signal combination circuit, a motor position signal xm as a present-position measurement value of a motor, and then the control-target position signal xfbis fed back to a position control circuit. Thereby, a torque command signal indicating a torque target value for driving the load is outputted.
