  • Abstract
    Flux estimation in induction machines is examined from the viewpoint of observer theory. It is pointed out that estimators presently used in connection with schemes such as field-oriented control are typically real-time simulations of machine equations, without feedback of any corrective prediction error. It is shown that corrective feedback can be used to speed up convergence of the flux estimates. It can also reduce the sensitivity of the estimates to parameter variations
