Simulation Research on SVPWM Control of Three-phase Permanent Magnet Synchronous Motor

利用Matlab/Simulink搭建了三相永磁同步电机的数学模型,对电机带载、加速、变速三种工况进行建模仿真,分析其在三种工况下的三相电流波形、转矩波形、转速波形.结果表明,基于电机矢量控制算法的永磁同步电机具有非常优秀的动静态控制性能.

The mathematical model of three-phase permanent magnet synchronous motor was established by using Matlab/Simulink in this paper.The three working conditions of motor load,acceleration and speed change are modeled and simulated.And the simulation results of the three-phase current waveforms,torque waveform,speed waveforms under three conditions were obtained.The results show that the permanent magnet synchronous motor based on motor vector control algorithm has excellent dynamic and static control performance.
