开发可靠、平稳、精确的无位置传感器启动程序是开关磁阻电机控制的重要组成部分。本文提出的无传感器启动方法具有优良的性能，并且不需要额外的硬件或内存。此外，提出的无传感器技术扩展到旋转轴条件。这些功能是汽车应用的高度要求，如起动/交流发电机和电动助力转向系统。评估了电机参数和诊断信号测量对无传感器启动方法质量的影响。这将有助于实践工程师对所建议的技术的实现做出明智的选择。实验和理论结果包括验证我们的主张。
Development of a reliable, smooth, and precise position sensorless startup routine is an integral part of the switched reluctance machine (SRM) control. The proposed sensorless startup method presented in this paper presents high grade performance and does not require additional hardware or memory. Further, the proposed sensorless technique is extended to rotating shaft conditions. These capabilities are highly demanded by automotive applications such as starter/alternator and electric power steering systems. An assessment of the impact of motor parameters and diagnostic signal measurement on the quality of the sensorless startup method is also included. This will help practicing engineers to make judicious selections for implementation of the proposed technique. Experimental and theoretical results are included to validate our claims.
