Universal Speed and Flux Estimator for Induction Motor

In the paper the concept of the universal speed and flux estimator with additional parameters estimators is presented. Proposed solution is based on the MRAS type flux and speed estimator and is dedicated for automotive applications. Induction Motor (IM) parameters are estimated using systems based only on the simple simulators and adaptive systems (voltage model and current model). Proposed system was tested in the sensorless induction motor drive with DFOC algorithm. Simulation and experimental results were presented in the paper.
