Experimental implementation of low-cost and robust sensorless control based on SOGI-FLL estimator for electric vehicles

Sensorless control techniques of electric motor dedicated to vehicles (EVs) offer low-cost and high operating performance. In this paper, a robust speed-sensorless scheme based on second-order generalized integrator-frequency-locked loop method (SOGI-FLL) is proposed with only one current sensor. The SOGI-FLL introduced estimate accurately the angular speed from measured signal. While scalar technique, single regulation, used determine <em>‎</em>control signals. According scheme, overall system will be very effective in terms easy practical implementation, which have great impact vehicle applications. dSPACE micro labox platform implement drive an induction motor. obtained results confirm effectiveness performance properly
