Abstract :
Observers are used in relation to several controllers: IFOC, sensor-less drives and for fault detection but they have not been used yet for predictive control of drives. This paper shows the benefits of incorporating a rotor current observer to enhance the predictions needed for predictive control of stator currents in VSI driven IM. The new scheme is compared with the standard one in which non-measurable variables are lumped into one term that is updated using a simple error tracking idea.
