本文提出了一种永磁同步电动机场路耦合参数自适应建模方法。该模型综合了数学模型和磁场模型的优点。它考虑了磁饱和，电流谐波，交叉耦合，涡流，和磁滞损耗的影响，从JMAG有限元分析（JMAG-FEA）工具中获得相应的自适应参数的模型。为了验证所提出的模型的有效性，三种建模方法进行了比较研究，通过离线仿真。此外，还搭建了一个基于DSP和dSPACE的控制器组合的半实物仿真实验平台，并将三个模型分别放置在该平台上。仿真和半实物仿真实验结果验证了模型的正确性和电机设计与控制一体化方案的可行性。此外，该模型与实际机器非常接近，可以根据不同的要求方便地进行定制。
A field-circuit-coupled parameter adaptive modelingmethod for a permanentmagnet synchronous motor is proposed in this paper. The model combines the merits of amathematical model and amagnetic fieldmodel. It takes into consideration the magnetic saturation, current harmonics, cross coupling, eddy current, and hysteresis loss effect in terms of the corresponding adaptive parameters obtained from the JMAG-finite element analysis (JMAG-FEA) tool in the model. To validate the effectiveness of the proposed model, three modeling methods are comparatively studied through an offline simulation. In addition, a hardware-in-the-loop experiment platform is built combining one DSP-based controller and a dSPACE-based controller, where the three models are located. The results of both, the simulation and HIL experiment, demonstrate the accuracy of the proposed model and the feasibility of the integration scheme of motor design and control. Moreover, the proposed model approximates the actual machine well and can be customized conveniently according to different requirements.
