Abstract:
In this article, signal errors of two multispeed resolvers and the measurement error incurred due to the signal errors are analyzed, and expressions for the errors are determined. Expressions for the position error due to amplitude imbalance, quadrature error, inductive harmonics, reference phase shift, excitation signal distortion, and disturbance signals are developed. From these expressions, bounds on the position accuracy achievable in practical resolver-based position sensing systems are determined. The correctness of the analysis results and experiments are also verified. The measurement accuracy of two multispeed resolvers (32-pole and 4-pole) is calculated as two appropriate case studies
