摘要
开关磁阻电机因其结构简单坚固、性能可靠、调速性能好等优点,在众多领域有着广泛的发展前景。要想获得良好的电机控制性能,转子位置信息的准确获取是不可或缺的。位置传感器的存在增加了系统的复杂性,降低了系统的可靠性。本文通过构建二阶滑模观测器,利用电机反馈的电压、电流值对转子的转速和位置进行估算,并对结果进行了仿真验证,证明了方法的可行性。
Switched reluctance motor because of its simple structure,reliable performanee,the advantages of good performance of speed adjustment,has a broad prospect in m^ny fields.In order to get a good motor control performance,accurate rotor position information acquisition is indispensable.But the existenee of position sensor in creases the complexity of the system,and reduce the reliability of the system.In this paper,by construct!ng the second-order sliding mode observer,using the motor feedback of voltage,current value to estimate the rotor speed and position,and has carried on the simulation,the results prove the feasibility of the method.
