摘要
针对电动汽车安全舒适、低压大功率的要求,文中分析了相移30°双三相永磁同步电机结构及工作原理,阐述了自然坐标系与双d-q坐标变换、矢量空间解耦变换旋转坐标系下的数学模型,并在Matlab/Simulink环境中搭建了双d-q坐标变换仿真模型与矢量空间解耦变换仿真模型,且对两种模型的仿真结果进行了对比。仿真结果验证了理论分析的有效性,理论分析及仿真模型的建立对于高性能电动汽车的研究开发具有重要意义。
In view of the safety and comfort of the electric vehicle and the high power of low voltage,the geometry and operational principle of dual three-phase permanent magnet synchronous motor with 30° phase shifting were analyzed,mathematical models of natural coordinate system and dual d-q coordinate transformation and vector space decoupling transformation were demonstrated,the simulation models of dual d-q coordinate transformation and vector space decoupling transformation were built in Matlab/Simulink environment,and simulation results of these models were compared.The simulation results verify the validity of the theoretical analysis,and the theoretical analysis and simulation model are of great significance for the research and development of high-performance electric vehicles.
