Field weakening implementation in AC induction machine predictive control

Abstract

AC induction motors become very popular for motion control applications due to their simple and reliable construction. Control of drives based on AC induction motors is a quite complex task. In most high-performance applications classical vector control is currently used. While this control method is usually reliable it has some limitations especially in controllers tuning and constraints handling. In the current paper we present an AC induction machine control method based on model predictive control including field weakening strategy. The proposed control algorithm has been proved and successfully verified in simulation.
