PROBLEM TO BE SOLVED: To provide a motor-driven power steering device for preventing a steering wheel from vibrating in case of a high gain of inertia compensation by detecting steering torque according to twisting of a link shaft for linking an input shaft combined with a dirigible road wheel to an output shaft combined with a steering mechanism, and adding drive current for compensating a phase of the torque. SOLUTION: As the gain of inertia compensation increases, a frequency characteristic the phase compensation is changed into a higher frequency and inertia compensation current corresponding thereto is generated and added to drive current for a motor, to thereby prevent a steering wheel from vibrating. |
