SOLUTION: A current command value operating unit 25 has an angular velocity difference compensation operating unit 36 to operate the angular velocity difference compensation Ir* which is a corrective component of the current command value Iq* based on the difference between the steering angular velocity ωw of the steering and the converted angular velocity ωm' of the rotational angular velocity ωm of a motor 12 converted into the value corresponding to the steering angular velocity of the steering (angular velocity difference ωr=ωs-ωm'). The current command value operating unit 25 outputs the angular velocity difference compensation Ir* superposed on the basic assist quantity Ias* which is the basic control quantity of the assist force to a motor control signal output unit as the current command value Iq*.
