Multi-domain co-simulation with numerically identified PMSM interworking at HILS for electric propulsion

In this paper, design and analysis of interior permanent magnet synchronous motor for electric vehicle bus propulsion is performed based on Finite Element Method. As the increase of the advanced application which requires precise control, the inverter is regarded as requisite for controlling electric machines. In addition multi-domain co-simulation is important to consider the inter-linking effect of the system as well as the conventional sinusoidal input analysis to investigate the characteristics of electric machines, specifically. Therefore, Multi-domain co-simulation is performed to consider the effect of inverter current, containing time harmonics, to the characteristics of interior permanent magnet synchronous motor in system circumstance. Simulated result is validated by comparing it with experimental result. Lastly, virtual driving test using Hardware-in-the-loop simulation is performed with co-simulated data to verify the reliability of multi-domain co-simulation model in virtual driving system.
