Position sensor signal in field orientation based permanent magnet synchronous machine control is a crucial signal for optimal control (average torque and torque ripple). With the unprecedented level of integration of the machine, and drive, numerous factors influence the harmonic content of the position signal. This paper outlines a preliminary discussion on the influence of these harmonics and presents the position harmonic relationship to output torque ripple through analysis, simulation and experimental data. Further, the effect of control system parameters that influence the behavior of harmonic propagation is also discussed. Controller bandwidth, harmonic order and motor speed are among the major factors that influence the output torque ripple due to position harmonics.
