Abstract
This paper proposes a strategy to minimize the losses
of an induction motor propelling an electric vehicle (EV). The
proposed control strategy, which is based on a direct flux and
torque control scheme, utilizes the stator flux as a control variable,
and the flux level is selected in accordance with the 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 are taken into account. Simulation 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.
