Vector control of a permanent magnet synchronous machine with a reluctance torque

摘要

The method involves determining imposed flux and torque generating current components, determining voltage components in and perpendicular to the flux direction, generating reduction values depending on deviations from voltage threshold values, generating field and torque generating current components with reluctance and generating a stator voltage vector from the determined voltage components in and perpendicular to the flux direction. ??The method involves determining imposed flux and torque generating current components depending on a detected revolution rate and a delivered torque, determining voltage components in and perpendicular to the flux direction depending on the imposed current component and on field and torque generating current components of a detected stator current vector, generating reduction values depending on deviations from voltage threshold values for limiting the delivered torque and a default current component, generating field and torque generating current components with reluctance depending on imposed current components and generating a stator voltage vector from the determined voltage components in and perpendicular to the flux direction.
