A Loss-Minimization DTC Scheme for EV Induction Motors

Abstract : This paper proposes a strategy to minimize the losses of an induction motor propelling and Electric Vehicle (EV). The proposed control strategy, based on a Direct Flux and Torque Control (DTC) scheme, utilizes the stator flux as control variable and the flux level is selected in accordance with torque demand of the EV to achieve the efficiency optimized drive performance. Moreover, among EV's motor electric propulsion features; the energy efficiency is a basic characteristic that is influenced by vehicle dynamics and system architecture. For this reason, the EV dynamics is taken into-account. Simulations tests have been carried out on a 1.1-kW EV induction motor drive to evaluate the consistency and the performance of the proposed control approach.
