MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD

摘要

A motor control device includes a switching element for controlling a motor, a current control unit for outputting a PWM signal to drive the switching element, and a setting unit for setting a carrier frequency for the PWM signal. Further, the motor control device includes a torque ripple compensation unit for setting a torque ripple compensation value on the basis of a motor torque command value, a carrier frequency, and the rotational state of a motor. The current control unit outputs a PWM signal on the basis of the motor torque command value and the torque ripple compensation value.
