摘要

本文建立了开关磁阻电动机在不同转子位置时的非线性磁链/电流特性的解析模型。该模型的独特之处在于转子位置的估计算法简单。因此，使用该分析模型实现了SRM的无传感器驱动。当转速在1:20的范围内变化，外加载荷从0到100%变化时，SRM在不同工况下转子位置的估计是非常稳定的。因此，获得了良好的性能，并详细报道了无传感器驱动。

Developing a sensorless approach for switched reluctance motors from a new analytical model

In this paper, a new analytical model for the nonlinear flux-linkage/current characteristics of the switched reluctance motors (SRM) at different rotor positions is proposed. The uniqueness of the model lies in a simple algorithm for estimating the rotor position. Hence, a sensorless drive of the SRM is implemented using this analytical model. The estimation of the rotor position under different operating conditions of the SRM is found to be very stable when the speed is varied within a ratio of 1:20 and the applied load is changed from 0 to 100%. Thus, excellent performance of the sensorless drive is obtained and is reported in details.
