Real-time FPGA model in the loop analysis of Permanent Magnet Synchronous Machine for LEV

The paper details an advanced analysis of a Permanent Magnet Synchronous Machine, as traction motor for light electric vehicles. The focus of the paper is to create a real-time model in the loop (RTMiL) simulator based on Field Programmable Gate Array (FPGA). By this, the gap between the simulated models and the behavior of the real machine and its converter is diminished. The machine with its electronic converter will be modelled on one FPGA and the control unit, with Field Oriented Control, on a second one. The communication between these devices is performed via the digital and analog I/Os. Hardware tools from National Instruments are used and the FPGAs are programmed using LabVIEW FPGA graphical programming environment. The results of the RTMiL analysis will be compared to those obtained by finite element models, benchmarking the strength of such real time simulators.
