摘　　要：在分析永磁同步电机控制系统原理的基础上,运用坐标变换的数学建模方法和空间矢量脉宽调制技术建立了永磁同步电机矢量控制系统的仿真模型。通过仿真软件MATLAB/Simulink进行仿真和电机性能分析表明,闭环矢量控制系统仿真方法准确、可行。在LABVIEW中搭建PMSM试验台并对电机性能进行测试,验证了PMSM建模与仿真的真实可靠性。Based on the analysis of control system working principle of the permanent magnet synchronous motor,the authors establish the simulation model of PMSM vector control system by use of the coordinate transformation of mathematical modeling method and space vector pulse width modulation technology.Simulation and performance analysis of the motor in MATLAB/Simulink software verify accuracy and feasibility of the closed-loop vector control system simulation method.A PMSM test bench is constructed in the LABVIEW,in which motor performance is tested,verifying the authenticity of the PMSM modeling and simulation.
