Assessment of Electric Drive for Fuel Pump using Hardware in the Loop Simulation

Abstract

The present communication deals with the evaluation of electric drives used in fuel system by using Hardware In the Loop (HIL) methodology. At the designing stage of electric drive, there are a lot of choices concerning electric motor technology (DC motors, AC motors, BLDC motors, PMSP motors) while there may be a lot of uncertainty in working environment, mission profile and control strategy at fuel pump level. For these reasons, HIL is suggested as solution that permits to test different motor technologies regardless the applied load. The outcome of HIL will be the most effective motor for studied application. Thermal model and power supply model are presented in this paper to be integrated in real-time model with tested electric motor model, to get virtual prototype closer to the real system. As a result, observations and restrictions of HIL methodology are presented, which point up the impact of the selection of the real motor and its drive.
