Abstract :
The paper presents a model-based predictive current regulator for a vector-controlled induction motor drive. An extended Kalman filter is employed to estimate the back EMF of the machine stator circuit model used by the inner current regulator loop. This also estimates the rotor resistance for slip angular velocity calculation in the outer speed loop. The adaptive feature of this controller leads to improved speed response performance from the induction machine
