一种新的SRD特定位置检测方法

介绍一种新的SRD位置检测方法。这种检测方法利用SRM定子与转子不相重叠区域内的电感特性,能够在各相的相导通周期中精确地检测到SRM的转子和定子开始重叠的位置。与传统方法相比,该方法只需存储少量参数(转子和定子开始重叠时的电感值以及相绕组电阻值),且精度高,成本低,适用范围广。仿真结果证明了该方法的有效性。

This paper describes a new SRD position detection method.This detection method uses the the inductance character- istics within theoverlapping area of the rotor and the stator,and can accurately detectthe position of the rotor and the stator of SRM starting to overlapin the respective phase of the phase conduction cycle.Compared with traditional methods,the method needs to store only a few parameters,which inductance values in the overlap of the rotor and stator phase winding resistance value,with high precision,low cost,wide application.The simulation results show the effectiveness of the method.
