摘要: 建立了基于永磁同步电机( PMSM)的电动助力转向(EPS)模型。由于PMSM固有的非正弦磁通分布、齿槽效应和电流检测误差等因素导致了明显的转矩脉动,因此根据寄生转矩脉动多是转子位置的周期函数和EPS系统中电机转速并非恒定不变的特点,提出了一种基于转角的迭代学习控制算法来抑制EPS中PMSM的转矩脉动,并对此进行了大量的仿真和实验验证。实验结果表明,该方案对EPS转矩脉动具有显著的抑制效果。

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.

Key words: permanent magnet synchronous motor (PMSM), electric power steering(EPS);iterative learning control (ILC), torque ripple
