A control device for restoration of a motor driven power steering (MDPS) system comprises a controller and a disturbance compensator. The controller receives an error between the speed of a target steering column and the speed of a real steering column and on the basis of the error, controls an MDPS system model, which is modeled on an MDPS system, to output a command for a target steering column speed corresponding to a restoring control torque command. The disturbance compensator compensates for disturbance contained in the output of the MDPS system model and provides the same to the output of the controller. The output of the MDPS system model is fed back to an input of the controller.

    MDPS(Motor Driven Power Steering) 시스템의 복원 제어장치는, 제어기 및 외란 보상기를 포함한다. 제어기는 목표 스티어링 컬럼(steering column) 속도와 실제 스티어링 컬럼 속도 사이의 오차를 입력 받아 상기 오차에 근거하여 MDPS 시스템을 모델링한 MDPS 시스템 모델이 복원 제어 토크 명령에 대응하는 목표 스티어링 컬럼 속도 명령을 출력하도록 제어한다. 외란 보상기는 MDPS 시스템 모델의 출력에 포함된 외란을 보상하여 제어기의 출력에 제공한다. MDPS 시스템 모델의 출력은 제어기의 입력에 피드백(feedback)된다.
