Abstract

The paper deals with the speed sensorless induction motor drive with MRAS type speed and flux estimator. The proposed control structure has been equipped with additional estimator of the magnetizing reactance reconstruction. Methodology is based on the well known mathematical interpolation of the inverse magnetizing curve. Dynamical performances of the vector control system with the current-type MRAS estimator with magnetizing reactance estimator are tested in simulation and in the laboratory set-up. Control structure is checked in the low speed and in the field weakening regions.
