Original Abstract Submitted

According to some embodiments, a method for controlling a motor comprises receiving mechanical angle data and electrical angle data representing a position of the motor, setting an encoder offset between the mechanical angle data and the electrical angle data, determining extremum values of a phase current of the motor, adjusting the encoder offset based on the extremum values to generate an adjusted encoder offset, determining an estimated motor position and an estimated motor speed based on the mechanical angle data, the electrical angle data, and the adjusted encoder offset, and generating a drive signal for the motor based on the estimated motor position and the estimated motor speed.
