Claim 0:
1. A vibration reduction apparatus of an MDPS (Motor Driven Power Steering), comprising:
an adaptive control module configured to detect an error signal, generated by disturbance, from a torque signal of a torque sensor which senses torque of the MDPS, and generate a compensation signal for compensating for a disturbance signal by using the error signal; and
an adaptive filter module configured to generate a filter signal by using a vibration frequency of the disturbance of the MDPS, remove a disturbance component of a current command outputted from an MDPS controller, on a basis of the filter signal, and output a current command in which the disturbance is suppressed,
wherein the MDPS controller generates a final current command on the basis of the compensation signal and the current command in which the disturbance is suppressed, and controls a motor of the MDPS according to the final current command.
