Accurate position estimation in switched reluctance motor with smooth starting

This paper presents a novel method of position estimation for switched reluctance (SR) motors. The method is suitable from starting to full speed. It ensures smooth starting without initial hesitation. The method further proposes a better position estimating algorithm incorporating corrections for eddy current and mutual inductance effects. The algorithm is better suited in a digital control platform for its realisation. In the present work, a Texas Instruments made DSP (TMS320c50) is used for the position estimation as well as control of the SR motor.
