摘要
提出了一种基于开关频率载波信号注入的永磁同步电动机的位置辨识新方法。该方法注入的高频旋转电压矢量的频率为开关频率,其优点是由于载波频率远离系统的速度环带宽,甚至远离电流环带宽,使得载波对系统的影响变得极小,辨识速度很快。给出了系统实现的详细算法和实验结果。实验结果符合理论分析。
A novel PMSM rotor position extraction method based on switching frequency carrier signal injection was presented.The carrier signal frequency was the switching frequency derived from the PWM inverter.The merit of this method includes little influence of carrier signal on system,because the carrier frequency is far from system speed loop and current loop bandwidth,and the position extraction speed is more quickly.Experimental results can confirm the effectiveness of the technique.
