一种具有快速磁链-转矩转换的开关磁阻电机简化磁链模型
A simplified flux linkage model of switched reluctance motor with fast flux-torque conversion
摘要
Abstract
In view of the difficulty in rapidly acquiring the phase flux linkage and phase torque of a switched reluctance motor(SRM)during operation,a simplified SRM flux linkage model is proposed,which can quickly and accurately calculate the motor's phase flux linkage and phase torque.First,different coupling coefficients ε are adopted in the proposed modeling strategy to fit the measured curves at each angle,which effectively improves the accuracy compared to the low-order Fourier decomposition method.Second,to address the problem of inaccurate flux linkage data caused by friction coefficients and measurement errors during the operation of the motor in manufacturing process,a compensation strategy based on the motor's acceleration loop is proposed,further improving the accuracy of the flux linkage model.Finally,the phase current waveforms obtained from the third-order Fourier magnetic flux model and the proposed magnetic flux model under different control strategies are compared on a 12/8 SRM,verifying that the proposed method achieves higher modeling accuracy.关键词
