Abstract

This paper proposes an improvement in the induction machine vector control thanks to an on-line estimation model of the induction machine. The estimation model consists of a thermal model providing the stator and rotor temperatures and a deep-bar effect model providing the updated rotor parameters. The tuned parameters are introduced into the 5 vector control equations improving in this way its accuracy.
