A feedforward control section computes, on the basis of a target current absolute value, a voltage limit value of a motor drive circuit, and a rotational speed ωr of a motor, a phase angle of a voltage vector which represents the output voltage of the motor drive circuit by a d-q coordinate system, the phase angle being a phase angle in relation to the d-axis of the d-q coordinate system.
