摘要:
[Problem]
An object of the present invention is to provide an electric power steering apparatus that suppresses a handle vibration (noisy sound) being caused by a handle inertia and a spring nature of a torsion bar and improves a steering feeling, without changing of the gain of the PI control.
[Means for solving the problem]
The present invention is an electric power steering apparatus that assist-controls a steering by driving a motor with a current command value calculated based on at least a steering torque, comprising a vibration-damping compensating section that calculates a vibration-damping compensation command value for suppressing a vibration of a handle based on a motor velocity of the motor, wherein the current command value is corrected by the vibration-damping compensation command value.
