Abstract
The present invention relates to an electric power steering apparatus and a method of controlling the same. The electric power steering apparatus includes an electric power steering apparatus including a steering motor that assists the steering force of the steering wheel; a position sensor that measures the rotational angle of the steering motor; an angle sensor that measures the rotational angle of an output end of an output shaft connected to the steering wheel; a compensation unit that calculates the difference between an angular speed of the steering motor and an angular speed of the output end of the output shaft by using the rotational angle measured by the position sensor and the rotational angle measured by the output end of the output shaft; and a steering control unit that controls a current input to the steering motor to compensate for the difference between the angular speed of the steering motor and the angular speed of the output end of the output shaft, according to the calculation result from the compensation unit. Accordingly, responsiveness and stability can be improved during a steering operation of a steering wheel by decreasing the difference between the rotat…
