A torque ripple compensation apparatus including a torque measurement unit configured to output torque measured through a torque sensor of an MDPS system; a motor speed measurement unit configured to output motor speed measured through a position sensor of an MDPS motor; a control unit configured to separately output an offset signal and a torque ripple signal based on the motor speed information and the measured torque information; and a torque ripple compensation unit configured to synthesize a plurality of torque ripple signals outputted from the control unit, and output a torque ripple compensation signal as a motor control signal to the MDPS motor, the torque ripple compensation signal being used to compensate for the synthesized torque ripple signal.
