Abstract

See full text

A control circuit controls driving of a motor to switch over a shift range. A target rotation speed setting part sets a target rotation speed of the motor. A rotation speed detection part detects a present rotation speed, which is an actual rotation speed, of the motor. A rotation speed error calculation part calculates a rotation speed error, which is an error between the target rotation speed and the present rotation speed. A request torque calculation part calculates a request torque for the motor based on the rotation speed error. A phase lead correction value calculation part calculates a phase lead correction value of a current supply phase relative to a rotation phase of a rotor of the motor based on the request torque.
