Switched reluctance initial rotor position estimation

摘要

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

1. A method of estimating an initial rotor position of a switched reluctance (SR) machine having a rotor and a stator, comprising the steps of:
driving a phase current in each of a plurality of phases of the SR machine to a predefined limit; performing an integration of a common bus voltage associated with each phase; determining a flux value for each phase based on the integrations; determining the initial rotor position based on the flux values; determining a middle flux value based on relative magnitudes of the flux values; determining the phase corresponding to the middle flux value; and determining the initial rotor position based on the middle flux value and the corresponding phase.
