Silent and parameter independent Hybrid Sensorless Control for SPMSM based on Current Oversampling

This paper proposes the combination of an Over-sampling based Arbitrary Injection Scheme with a novel Over-sampling based EMF estimation approach for SPMSMs, whichboth are free of machine parameters. The Oversampling basedEMF estimator is furthermore unaffected by IGBT interlocktime. The combination strategy is based on a signal-to-noise-ratioconsideration, which concludes the whole hybrid scheme beingcompletely free of machine parameters and therefore applicableto any SPMSM without configuration.     «
