Claim 7:
8. A motor control device comprising:
a motor; and
an electronic control unit (ECU) that generates a torque command to be input to the motor;
wherein the motor is configured to receive voltage based on the torque command, and
the ECU is configured to:
estimate disturbance of the motor from a feedback value that is a control amount of the motor and voltage applied to the motor, and
estimate a delay from the torque command, the feedback value, and the disturbance,
stop estimating the disturbance of the motor while the motor is performing unloaded operation,
estimate a delay from the torque command and the feedback value while the motor is performing unloaded operation, and
control rotation of the motor based at least in part on the torque command,
wherein the delay is set to the voltage.
