中文摘要：
为了实现面贴式隐极永磁同步电机零速下转子初始位置的检测,从电机的高频数学模型出发,引入适合脉振高频注入法实现无传感器运行所需的定子槽磁桥特殊结构,分析了定子槽形和定子槽磁桥尺寸对电机饱和凸极效应的影响,并通过有限元分析予以验证,获得了高频阻抗随转子位置的变化规律,提出零速下无转子位置/速度传感器的控制策略.仿真结果表明这种基于饱和凸极转子位置检测原理的无速度传感器控制对面贴式永磁同步电机零速下定位及运行控制的正确性和可行性.
英文摘要：
in order to detect the initial rotor position of a surface mounted permanent magnet synchronous motor （SMPMSM） at zero-speed. Started with the high-frequency model of SMPMSM, the particular configuration of stator slot-bridge is introduced, which is suitable for high-frequency signal injection. Then the influence of the stator slot-bridge structure and dimension on the magnetically saturated saliency was analyzed and verified by the finite element analysis （FEA）. Meanwhile, the spatial impedance variation with the rotor position was also analyzed and acquired, which formed the basis of the saliency-based sensodess control strategy at zero-speed. Finally, the simulation investigation showed the correctness and feasibilities of the saliency-based sensorless control of SMPMSM at zero-speed operation.
