An Improved Sensorless DTC Scheme for EV Induction Motors

Abstract

In this paper a sensorless control is proposed to increase the efficiency of a direct torque control (DTC) of an induction motor propelling an electric vehicle (EV). The proposed scheme uses an adaptive flux and speed observer that is based on a full order model of the induction motor. Moreover, it is evaluated on an EV global model taking into account the… (More)
