摘要
本文提出了一种基于DSP的隐极电机的无位置传感器的矢量控制方法。本算法充分利用了隐极电机的特性来进行近似地估计转子的位置,大大减低了算法的运算量。此外,本算法还巧妙地利用了α-β轴磁链的极性来近似估计转子的运行速度,实现了完整的无位置传感器的矢量控制。文章最后给出了本算法基于TMS320F2812 DSP的实现。
A sensorless vector control method based on TMS320F2812 is presented for surface mounted permanent magnetic synchronous motor. . Using the characteristics of SPM to estimate the rotor position, this algorithm makes it easier to get the rotor position. Besides, this algorithm uses the polarity of flux linkage in α-β axes to calculate the actual rotor running speed. In this case a whole sensorless vector control is implemented. To confirm the effectiveness of the proposed algorithm, the implementation based on TMS320F2812 is described and some experimental data and wave are listed.
