Abstract :
In the paper the Model Reference Adaptive System (MRAS) type estimator is applied in the sensorless Direct Torque Control with Space Vector Modulation (SVM-DTC) of Induction Motor (IM) drive. Sensorless control algorithm is tested on the traction 50kW induction motor drive. Whole control structure was implemented in the laboratory set-up with DS1103 card with Power PC 750GX DSP processor using C language. Dynamical performance of the drive and the estimator properties in field weakening and low speed regions for traction drive system are presented.
