摘要
本文首先讨论了开关磁阻电机电流～磁链～位置关系的基本原理,给出了一种基于能量优化的磁链法的间接位置检测方案,然后推导出开关磁阻电机的平均扭矩最大化的数学模型,最后利用MATLABL仿真出不同转速下的最优开关角。
This paper introduces the basic theory of the switched reluctance drives.And a sensorless technique for SRD based on the flux method with energy optimizing strategy is proposed.The optimal turn-on and turn-off angle at different rotate speed are then obtained by simulation.
