Abstract
A compensation control apparatus of motor driven power steering may include: a torque sensor for measuring a driver's column torque inputted to a steering wheel; and a controller for generating an assist torque based on the column torque measured through the torque sensor, compensating for a phase margin in a low-frequency band for the generated assist torque, detecting a resonance frequency to attenuate resonance, and outputting a final assist torque.
