A F/B gain control unit (47) computes a first change component (d¸Ä) by executing torque feedback control based on a torque deviation (T) using a feedback gain that is computed by a F/B gain variable control unit (80). The F/B gain variable control unit (80) computes one of two different feedback gains (K1, K2) that correspond to a "first computation mode" in which the first change component (d¸Ä) is used as an addition angle (¸a) and a "second computation mode" in which a value obtained by correcting the first change component (d¸Ä) by an estimated motor rotation angular velocity (Ém_e) is used as the addition angle (¸a), respectively. A feedback gain (K1) used in the first computation mode is set such that a response at the feedback gain (K1) is higher than that at a feedback gain (K2) used in the second computation mode.
