永磁同步电机矢量控制系统MTPA控制实现

The MTPA control of the PMSM FOC system

分析了永磁同步电机矢量控制系统最大转矩电流比控制,并给出了一台15kW内置式永磁同步电机矢量控制系统分别在i_d=0控制和最大转矩电流比控制下的实验结果。实验结果表明,相比较于i_d=0控制,最大转矩电流比控制可减小定子电流,从而减小电机和逆变器损耗。

The maximum torque per ampere （MTPA） control of the permanent magnet synchronous motor （PMSM） vector control （VC） system is analyzed. The experiment results of a 15kW interior PMSM FOC system under the MTPA control and the id =0 control are given. The experimental results show that comparing with the id =0 control, the MTPA control can decrease stator current. Furthermore, decrease the losses of the motor and inverter.
