Sensorless Scalar Control Based On SOGI-FLL for an Induction Motor U sed in Electric Vehicle

Abstract

This paper, present a sensorless scalar control for its application to an induction motor used in electric vehicle. as it is based on indirect motor speed estimation by using second order generalized integrator-frequency locked loop method Which in turn requires only one current sensor, Thus, the cost is can be reduced. The simulation results are presented to demonstrate the effectiveness of the proposed method.
