摘　　要：永磁同步电动机由于效率高、传动消耗小、噪音低、谐波少、结构简单、运行可靠、产生的电磁转矩精度高,常用于航空航天、轨道交通、人工智能、无人机等对调速性能要求较高的场合。其定子绕组与异步电动机定子绕组相同,转子采用永久磁钢,磁通恒定,对控制而言,电压方程、磁链方程和转矩方程都较异步电动机简单。论文首先在建立三相永磁同步电动机的动态数学模型之前做如下假设,忽略铁心饱和、涡流和磁滞损耗,忽略转子永久磁钢电导率,且定子侧相绕组中感应电动势及磁动势波形为正弦波。其次建立了二极面装式电压空间矢量PWM(Space Vector Pulse Width Modulation)的三相永磁同步电动机矢量控制系统,后续进行了基于Matlab/Simulink的建模与仿真,搭建了仿真平台。得到了在不同的给定转速及负载下,电机速度、电磁转矩及各相电流的变化趋势与波形。Permanent magnet synchronous motors are commonly used in aerospace,rail transportation,artificial intelligence,unmanned aerial vehicles and other applications requiring high speed regulation performance due to their high efficiency,low transmission consumption,low noise,low harmonics,simple structure,reliable operation,and high precision of the electromagnetic torque generated.Its stator winding is the same as the stator winding of asynchronous motor,and the rotor adopts permanent magnets with constant magnetic flux,which makes the voltage equation,magnetic chain equation and torque equation simpler than those of asynchronous motor for control.In this paper,firstly,the following assumptions are made before establishing the dynamic mathematical model of three-phase permanent magnet synchronous motor,core saturation,eddy current and hysteresis loss are neglected,rotor permanent magnet steel conductivity is neglected,and the waveforms of the induced electromotive force and magnetic dynamic potential in the stator side-phase windings are sinusoidal waves.Secondly,the vector control system of three-phase permanent magnet synchronous motor with two-pole surface-mounted voltage space vector PWM(Space Vector Pulse Width Modulation)is established,and the subsequent modeling and simulation based on Matlab/Simulink is carried out to build a simulation platform.The trends and waveforms of motor speed,electromagnetic torque,and currents of each phase are obtained at different given speeds and loads.
