摘　　要：内置式永磁同步电机(IPMSM)功率密度高,电感参数非线性变化较显著,针对此情况,基于高速FPGA芯片建立IPMSM的非线性模型,与真实控制器连接,构建硬件在环半实物平台。利用两台产品级车用永磁电机组成共直流母线的对拖平台,与所构建的硬件在环半实物平台进行对比,测试转速范围从恒转矩区到弱磁区,测试转矩从轻载到额定负载。试验结果表明:考虑电感饱和效应的电流查找表是有效的;在高速、重载运行时,系统获得较好的稳态性能,硬件在环平台是有效的,两个平台的平均误差为4.15%。The interior permanent magnet synchronous motor （IPMSM） for electrical vehicle has the characters of power density high, and nonlinear variation about parameters is significant. According to the situation, based on the FPGA chip, a nonlinear model of permanent magnet motor for electrical vehicle was built. The model connects to a real controller, and constructs the hardware-in-the-loop semi-physical real time simulation and test bench. Combined a common DC bus AC drive systems, the two sets of permanent magnet motors for electrical vehicle, which satisfy the need of industrial products, composed a drag bench. It contrast to the hardware-in-the-loop semi-physical real time simulation and test bench, test speed range from the constant torque area to the field weakening region, and the test torque range from lighter load torque to the rated load. The experiment results： voltage modulation does not come out, it satisfied that the current look-up table was effective. In high speed heavy duty operation, the system got good steady-state performance, which showed the hardware in the loop platform was valid, and the average error for twoed platform was 4.15% .
