测量和量化开关磁阻电机的电磁特性对于先进的电机控制和性能的提高是必不可少的。本文报道了一种在没有转子夹持装置和位置传感器的情况下获得开关磁阻电机磁链特性的方法。该方法将测量与数据重建相结合。在测量步骤中，间接测量了四个力矩平衡位置的磁链样品。考虑到相间的磁耦合，采用了两种不同的励磁形式，进一步提高了精度。然后，对于重构步骤，采用基于模糊逻辑的方法，根据测量结果重建完整的磁链特性。将施工结果与传统的转子夹紧方法的测量结果进行了比较，两者吻合较好，证明了该方法的有效性。在重构电磁特性的基础上，利用MatLab对一台开关磁阻电机样机在不同控制方式下进行了动态仿真分析。通过与动态实验的对比，进一步验证了该方法的准确性和有效性。
Measuring and quantifying the electromagnetic characteristics of switched reluctance motors (SRMs) are indispensable for advanced motor control and performance enhancement. This article reports on a novel method in obtaining the flux-linkage characteristics of an SRM without rotor clamping devices and position sensors. This approach combines measurement with data reconstruction. For the measuring step, flux-linkage samples at four torque-balanced positions were measured indirectly. Considering the magnetic coupling among phases, two different excitation forms were adopted to further increase accuracy. Then, for the reconstructing step, a fuzzy logic-based approach was applied to reconstruct the complete flux-linkage characteristics with measurement results. The construction results were compared to measurements results from the traditional rotor clamping method, and good agreements can be found, demonstrating the effectiveness of the proposed method. Furthermore, based on reconstructed electromagnetic characteristics, dynamic simulation of an SRM prototype under different control modes was carried out and analyzed in MATLAB. Comparison with dynamic experiments further verifies the accuracy and effectiveness of the proposed method.
