Abstract

This paper proposes the combination of an Oversampling based Arbitrary Injection Scheme with a novel Oversampling based EMF estimation approach for SPMSMs, which both are free of machine parameters. The Oversampling based EMF estimator is furthermore unaffected by IGBT interlock time. The combination strategy is based on a signal-to-noise-ratio consideration, which concludes the whole hybrid scheme being completely free of machine parameters and therefore applicable to any SPMSM without configuration.
