基于电感线性区模型的开关磁阻电机无位置传感器技术
Sensorless Control of Switched Reluctance Motors Based on Phase Inductance Model in Linear Regions
摘要
Abstract
Sensorless starting and low speed operation is a difficult research branch in switched reluctance motor (SRM). In this paper, the three modes such as the standstill, rotating shaft condition and the driving runming condition are considered. A sensorless control method is presented in this paper, which is based on the phase inductance model in linear region. In this method, the phase current slope difference calculation method is utilized for identifying the full-cycle inductance; based on the inductance characteristics, the inductance comparison logics are proposed for estimating the inductance linear region; and in the linear region, the position vs. inductance characteristics are modeled for estimating the rotor position and speed information, which can be used for sensorless starting and driving operation without hesitation. The experimental results verify the theoretical analysis and its validity.关键词
