New Correction Methods for Nonorthogonality and Amplitude Mismatch of Angle Position Sensor by Using Atan2-Function

This article introduces a new method to correct the nonorthogonality of an angle position sensor based on Atan2- function without determination of the phase shift. Furthermore, to compensate the nonorthogonality and amplitude mismatch a more accurate method is proposed by using principal component analysis. Moreover, the advantages and disadvantages of both methods are discussed, compared to the conventional methods.
