本文提出了一种新的无刷双馈磁阻电机（BDFRM）的无轴位置传感器实功率和无功功率独立控制算法，该算法在有限的变速范围应用（如泵或风力涡轮机）中具有竞争力。该算法的灵感来自于机器的基本操作原理，不依赖于任何参数。因此，它比基于模型的控制方法更鲁棒，后者经常受到与机器参数变化或其不准确识别相关的敏感性问题和性能权衡的影响。反过来，所考虑的控制方法仅依赖于并网绕组的电压和电流信号。包括速度跟踪、功率因数调节和负载响应在内的实际研究表明，该方案在定制设计的1.5 kW样机上具有高性能。
A new algorithm for shaft position sensor-less independent control of real and reactive power of the Brushless Doubly-Fed Reluctance Machine (BDFRM), an emerging competitive for applications with limited variable speed ranges (e.g. pumps or wind turbines), is proposed and experimentally verified in this paper. The algorithm is inspired by the fundamental operating principles of the machine and does not depend on any parameters. Therefore, it is more robust than model-based control approaches which often suffer from sensitivity issues and performance trade-offs associated with machine parameter variations or their inaccurate identification. In turn, the considered control method merely relies on the grid-connected winding voltage and current signals. Practical studies including speed tracking, power factor regulation and load response have demonstrated high performance of the scheme on a custom designed 1.5 kW prototype.
