说明：  源模型是从pudn下载，里边的双闭环控制能用但是没有理论依据且参数设计不合理，下垂控制模块也是有问题，重新改进过的(The source model is downloaded from the pudn. The double closed-loop control can be used, but there is no theoretical basis and the parameter design is unreasonable. The droop control module is also problematic and has been improved)

分析了永磁同步电机矢量控制的发展概况，然后从机电能量转换的角度出发，解释三相永磁同步电机的机电能量转换原理，推导拉格朗日运动方程。此外，列写出永磁同步电机在三相静止坐标系和dq坐标系下的数学模型。基于Simulink建立了转速电流双闭环矢量控制系统的仿真模型，通过对仿真结果分析，验证了永磁同步电机矢量控制系统性能的优越性(The development of vector control of permanent magnet synchronous motor is analyzed. Then, from the perspective of electromechanical energy conversion, the principle of electromechanical energy conversion of three-phase permanent magnet synchronous motor is explained, and the Lagrangian motion equation is derived. In addition, the mathematical model of the permanent magnet synchronous motor in the three-phase stationary coordinate system and the dq coordinate system is written. Based on Simulink, the simulation model of the speed and current double closed-loop vector control system is established. The simulation results are analyzed to verify the superiority of the performance of the permanent magnet synchronous motor vector control system.)
