ABSTRACT:
An apparatus controlling a velocity of a motor having a rotor, includes a sensing velocity calculator sensing a rotation velocity of the motor, and calculating a sensing velocity on the basis of the sensed rotation velocity of the motor; a velocity estimator estimating an estimation velocity of the motor based on an information about a position error of the rotor; and a reference velocity calculator dividing an overall velocity period of the motor into a plurality of unit velocity periods based on a command velocity for controlling the rotation velocity of the motor, calculating a sum of the sensing velocity, the estimation velocity, and the command velocity after multiplying at least one of the sensing velocity, the estimation velocity, and the command velocity by a predetermined weight, and outputting the sum as a reference estimation velocity of the motor.
