FPGA-based Real-Time Simulation of Five-Phase PMSM for the HIL Applications

Real-time simulation technology plays an important role in the development cycle of a permanent magnet synchronous motor (PMSM) control system. In this paper, an FPGA-based real-time simulation method is proposed for a five-phase permanent magnet synchronous motor (FPMSM). The mathematical model and its FPGA implementation are presented in detail. Moreover, to verify the accuracy of the model, the FPGA-based simulation results are compared with that of the FPMSM model in the Simulink Simscape Power System (SPS) library, and very good consistency is obtained. Finally, the dual-loop controller is implemented on FPGA and the real-time experiments of FPMSM control under various conditions are conducted to validate the effectiveness of the proposed FPGA real-time simulation method.
