Flux-observer-based high-performance control of synchronous reluctance motors by including cross saturation

A fully digital control scheme for synchronous reluctance motors is presented, based on a particular type of flux observer. This includes a quite accurate magnetic model of the motor, taking into account cross saturation. This model is first described and the practically obtained control performance...

Description
Summary:A fully digital control scheme for synchronous reluctance motors is presented, based on a particular type of flux observer. This includes a quite accurate magnetic model of the motor, taking into account cross saturation. This model is first described and the practically obtained control performance is then shown, giving evidence to the impact of such a model on the system behavior.
