Abstract
An induction motor controller is provided. The induction motor controller includes a first module that derives a commanded stator voltage vector, in a rotor flux reference frame, via a rotor flux regulator loop and a torque regulator loop, which process at least partially in the rotor flux reference frame. The induction motor controller includes a second module that processes the commanded stator voltage vector to produce AC (alternating current) power for an induction motor.
