摘要：

Tracking resolver-to-digital converters are often used with resolvers to form a high-accuracy position sensor. When resolver signals deviate from the assumed ideal, the converter output exhibits error, degrading position accuracy. In this letter, resolver signal-processing techniques are introduced that reduce or eliminate the position error incurred due to common resolver signal imperfections. In particular, a method is introduced that eliminates the error due to imperfect quadrature. In addition, several techniques are discussed that reduce the position error caused by resolver inductance harmonics.
