Motor Control Device and Electric Vehicle

Abstract

A motor control device includes: a current command value generation unit which generates a current command value based on a motor torque command value and a rotation speed of a motor; a torque command value calculation unit which calculates a torque command value based on the generated current command value and calculates a torque of the motor based on a detection value of a current flowing through the motor; a voltage phase control unit which controls a voltage phase angle such that the torque of the motor matches with the torque command value; and a power conversion unit which converts DC power into AC power based on the voltage phase angle and rotation angle information of the motor, and outputs the converted AC power to the motor. The current command value generation unit calculates a d-axis current command value or a q-axis current command value such that a current command value of any one axis of the d-axis current command value and the q-axis current command value constituting the current command value approaches a current detection value of the axis.
