ABSTRACT:
A universal field-oriented controller (UFO) for an induction machine drive is capable of decoupling flux and torque in an arbitrary flux reference frame. Transitions between reference frames, including rotor flux, stator flux and air gap flux, are made by changing the effective stator-to-rotor turns ratio. The UFO is capable of operating in a direct field-orientation mode and an indirect field-orientation mode without requiring additional hardware or software.
