Real-Time FPGA/CPU-Based Simulation of a Full-Electric Vehicle Integrated with a High-Fidelity Electric Drive Model

Real-time simulations refer to the of a physical system where model equations for one time-step are solved within same time period as in reality. An FPGA/CPU-based real-time simulation platform is presented this paper, with full-electric vehicle implemented central processing unit (CPU) board and an electric drive field programmable gate arrays (FPGA) board. It has been challenge interface two models different processors. In open-loop three closed-loop interfaces proposed. results show that best method transmit machine speed from derive model, feedback torque calculated FPGA. addition, virtual testing tool (CarMaker) used when building achieving more accurate modeling subsystems. The can be verify advanced control functions during hardware-in-the-loop (HIL) testing. Vehicle anti-slip example here. Finally, experiments were performed by connecting back-to-back test bench. Results torque, rotor speed, d&q axis currents all good agreement between experiments.
