摘要

提出了一种非侵入式的开关磁阻电机轴角估计方法。这种方法可用于开关磁阻电机的换相控制，从而消除了对轴位置传感器的要求。这些方法依赖于机器固有的磁通/电流磁特性，通过测量定子磁链和在法相激励时的电流来推断转子位置。提出了单相和多相同步激励的srm位置估计方案。本文还介绍了根据所提出的位置集总参数估计方案处理的实测SRM数据的模拟传感性能。

Flux-current methods for SRM rotor position estimation

A family of nonintrusive methods is presented for estimating the shaft angle of a switched reluctance machine. Such methods can be utilized for commutation control of the SRM (switched reluctance machine) thereby eliminating the requirement for a shaft position sensor. These methods rely on the machine's inherent flux/current magnetic characteristics to infer rotor position from measurements of stator flux-linkage and current during normal phase excitation. Position estimation schemes are presented for SRMs in which both single and multiple simultaneous phases are excited. Also presented is a simulated sensing performance using measured SRM data processed according to the proposed position lumped-parameter estimation scheme.<>
