基于转角的迭代学习控制策略下永磁同步电机EPS转矩脉动抑制方法
Torque Ripple Suppression of PMSM Applied for EPS Based on Motor Rotation Angle's ILC
摘要
Abstract
An EPS model was established based on PMSM.Due to factors such as the inherent non-sinusoidal magnetic flux distribution,cogging effects and current detection errors of PMSM,obvious torque ripples were caused.According to the characteristics that parasitic torque ripples were mostly a periodic function of the rotor position and the motor speeds in EPS system were not constant,an ILC algorithm based on corners was proposed to suppress the torque ripples of EPS in PMSM,and a large number of simulations and experimental verifications were carried out.The experimental results show that this scheme has significant inhibitory effects on the torque ripples of EPS.关键词
