High speed flux feedback for tuning a universal field oriented controller capable of operating in direct and indirect field orientation modes

Patent · Wed Jan 01 04:00:00 EST 1992

OSTI ID:868456

The direct (d) and quadrature (q) components of flux, as sensed by flux sensors or determined from voltage and current measurements in a direct field orientation scheme, are processed rapidly and accurately to provide flux amplitude and angular position values for use by the vector rotator of a universal field-oriented (UFO) controller. Flux amplitude (linear or squared) is provided as feedback to tune the UFO controller for operation in direct and indirect field orientation modes and enables smooth transitions from one mode to the other.
