SWITCHED RELUCTANCE INITIAL ROTOR POSITION ESTIMATION

摘要

A method (130) of estimating an initial rotor (110) position of a switched reluctance (SR) machine (106) having a rotor (110) and a stator (112) is provided. The method (130) may comprise the steps of driving a phase current (132) in each of a plurality of phases of the sr machine (106) to a predefined limit (134), performing an integration of a common bus (114) voltage associated with each phase, determining a flux value for each phase based on the integrations, and determining the initial rotor (110) position based on the flux values.
