提出了一种基于数字化虚拟电机的半实物实时仿真测试方法。利用FPGA构建了考虑空载损耗的内置式永磁同步电机( IPMSM)以及基于同步状态机的逆变器的虚拟电机系统。虚拟电机系统的仿真步长为1μs,逼近真实工况。采用dSPACE作为控制器,搭建了基于IPMSM虚拟电机系统的硬件在环( HIL)实时仿真平台。在四象限运行的车用电机实物平台上进行了电机的空载、负载工况下的矢量控制试验。通过与HIL试验结果的对比,验证了虚拟永磁同步电机系统的有效性和准确性。

A real-time hardware in loop simulation test method of digital virtual motor was proposed. A virtual IPMSM system model close to the real conditions was established based on FPGA, the simulation step of which was 1μs, including IPMSM model considering no-load loss and inverter model based on synchronous state machine. Using dSPACE as the controller, a hardware in the loop ( HIL) simulation platform of virtual IPMSM system based on FPGA was set up. The vector control experiments of no-load and load conditions had been done in the four quadrant operation physical platform of IPMSM for electric vehicles. By comparing HIL experimental results with physical platform results, the validity and accuracy of the virtual IPMSM system had been verified.
