论文摘要
我们通过使用PWM本身提供的激发来证明如何从测量的电流中恢复PWM控制的PMSM的转子位置。这提供了信号注入的好处,特别是即使在低速下运行的能力,而没有外部探测信号的弊端。我们通过模拟和实验结果来说明方法的相关性。
We demonstrate how the rotor position of a PWM-controlled PMSM can be recovered from the measured currents, by suitably using the excitation provided by the PWM itself. This provides the benefits of signal injection, in particular the ability to operate even at low velocity, without the drawbacks of an external probing signal. We illustrate the relevance of the approach by simulations and experimental results.
