使用高频 (HF) 载波注入可以在零速和低速下对磁阻同步机 (RSM) 进行无位置传感器控制。 RSM 的标准 d-q 模型揭示了基波电流不同工作点的机器参数差异很大：在设计基波电流控制器时需要考虑这一事实，以确保稳定性。类似地，高频电机参数变化很大，应该在估计转子位置的解调方案中予以考虑。本文展示了有效高频电感与标准基本模型电感的不同、它们如何受饱和影响以及如何利用这些知识来确保稳定可靠的无传感器控制。
Position sensorless control of the reluctance synchronous machine (RSM) at zero and low speed is possible using high frequency (HF) carrier injection. The standard d-q model of the RSM reveals greatly varying machine parameters for different working points of fundamental current: this fact needs to be taken into account in the design of the fundamental current controller to ensure stability. Similarly, the HF machine parameters vary greatly and should be considered in the demodulation scheme for the estimated rotor position. This paper shows that the effective HF inductances are different to the standard fundamental model inductances, how they are influenced by saturation and how this knowledge can be used to ensure stable and reliable sensorless control.
