针对五相永磁同步电机控制需要电流传感器数量多、成本高的问题,提出了一种五相永磁同步电机相电流重构方法。它只使用两个电流传感器便可实现对五相电流的全采集,能有效减少硬件电路的成本和复杂性,重构精度和速度能够满足五相电机控制的需要。最后在MATLAB仿真中对所提方法进行验证,仿真结果证实了所提方法的正确性和有效性。

[Abstract]
Considering the problem of over many current sensors used in fivephase permanent magnet synchronous motor control system, a new method of current reconstruction for fivephase permanent magnet synchronous motor was proposed. This method used only two current sensors to realize full acquisition of fivephase current, could effectively reduce the cost and complexity of the hardware circuit. The reconstruction precision and speed could meet the needs of fivephase permanent magnet synchronous motor control. Finally, the proposed method was validated in MATLAB. Results showed the correctness and effectiveness of the proposed method.
