The paper presents the experimental results obtained with a speed-sensorless FOC of an induction motor (IM) supplied by a PWM-Voltage Source Inverter (VSI). The speed tuning signal is estimated with a model reference adaptive system (MRAS) observer which uses the back e.m.fs quantities. Mamdani’s fuzzy logic controllers (FLC) are used for the speed controller and also for the MRAS controller.
