The present invention provides an apparatus for compensating for disturbance of a motor driven power steering (MDPS) system, comprising: a steering angular speed determination part determining whether a steering angular speed is generated by disturbance from a road surface; a column torque determination part determining whether column torque is generated by disturbance from the road surface; a torque change rate generation part generating a column torque change rate of the column torque; a compensation torque calculation part calculating compensation torque regarding disturbance using a determination result of the steering angular speed determination part, a determination result of the column torque determination part, and a column torque change rate of the column torque determination part; and a final assist torque output part generating final assist torque through assist torque of the MDPS system and compensation torque of the compensation torque calculation part and outputting the final assist torque. According to the present invention, undesired steering, which can be generated by kickback, can be prevented.

    본 발명은 조향각속도가 노면으로부터의 외란에 의해 발생된 것인지 여부를 판별하는 조향각속도 판별부; 컬럼토크가 노면으로부터의 외란에 의해 발생된 것인지 여부를 판별하는 컬럼토크 판별부; 컬럼토크의 컬럼토크변화율을 생성하는 토크변화율 생성부; 조향각속도 판별부의 판별 결과와 컬럼토크 판별부의 판별 결과 및 컬럼토크 판별부의 컬럼토크변화율을 이용하여 외란에 대한 보상토크를 산출하는 보상토크 산출부; 및 MDPS 시스템의 어시스트토크와 보상토크 산출부의 보상토크를 통해 최종 어시스트토크를 생성하여 출력하는 최종 어시스트토크 출력부를 포함하는 것을 특징으로 한다.
