Review of Sensorless Techniques of Switched Reluctance Motor Drives

In this paper, the status of researching on sensorless switched reluctance motor drives (SRD) is generally reviewed and its development trends are discussed. Until now, some methods have been proposed, which can be classified as the method based on the detection of the unexcited phase self-inductance, the method based on excited phase self-inductance detection, mutually induced voltage measurement method, the method based on the detection of attached coils or capacitors and so on. The advantage and disadvantage of these methods are discussed in detail within their applied domain. Today, the technology of sensorless SRD has drawn more and more attention. But it is unperfect, the research on the technology of sensorless SRM will be continuous to reduce the cost and improve the precision, reliability and robustness.
