Method and apparatus for distortion correction of motor shaft position signal in motor system with angle sensor during vehicle drive

摘要

The present invention relates to a method and apparatus for correcting a motor rotation speed by vibration in a motor system to which an angle sensor is applied, and more specifically, a sensing unit for sensing an axis angle of a motor through an angle sensor; A first control unit which determines whether the rotation speed needs to be corrected; And in response to the motor axis angle measured by the sensing unit corresponding to the angle boundary section at the moment when the first controller determines that the rotation speed is required to be corrected, the correction rotation speed is assumed to be an angle reference value. And a second control unit for correcting to a value subtracted from the corrected rotation speed when smaller than an angle reference value, and correcting to a corrected rotation speed when larger than an angle reference value. .
