摘要

众所周知，在多相驱动中，气隙磁场的空间谐波可以相互独立地控制。本文给出了如何在不需要机械传感器的情况下，利用磁场的三阶空间谐波来估计转子转速。实验结果证实了所研制的无传感器速度观测器的可行性。

Injection of third-order spatial field harmonics for sensorless speed estimation in multiphase induction motor drives

It is well-known that in multiphase drives the spatial harmonics of the air-gap magnetic field can be controlled independently of each other. In this paper it is shown how the third-order spatial harmonic of the magnetic field can be used to estimate the rotor speed without the need of a mechanical sensor. Experimental results confirm the feasibility of the developed sensorless speed observer.
