Abstract
A motor control device includes a feed-forward control unit configured to detect a change amount of any one of the target voltage, the applied voltage peak value, and the revolution number difference, which are a monitoring target. The control unit is also configured to manipulate an operation amount of a predetermined operation target on the basis of a magnitude of the change amount to correct the number of revolutions of the motor recognized by a controller.
