永磁同步电动机中的电流谐波会引起转矩脉动，降低运行稳定性，并引起振动和噪声，从而可能由于谐振现象而导致关键部件损坏.针对这一问题，本文提出了一种用于永磁同步电机电流环控制的改进自抗扰控制策略，以提高系统稳定性和抑制三相电流中的6k±1次谐波.该策略将改进态观测器与准谐振谐波抑制器相结合，以更好地观测和补偿5次和7次谐波干扰.此外，为了提高周期扰动的估计精度，引入了基于重复控制的扰动观测回路.从跟踪性能、干扰抑制能力和鲁棒性等方面对所提出的控制策略的性能进行了评估.仿真结果表明，该控制器的性能明显优于常规的PID控制器和传统的自抗扰控制方法，在抑制低次谐波、提高动态响应速度、增强系统的鲁棒性等方面具有明显的优势.通过永磁同步电机半物理实验平台验证了该控制策略对抑制三相电流中6k±1次谐波的有效性.
Abstract：Current harmonics in permanent magnet synchronous motors(PMSM) can lead to torque ripples, reduced operational stability, and induced vibrations and noise, which may cause critical component damage due to resonance phenomena. To address this problem, an enhanced active disturbance rejection control(ADRC)strategy for PMSM control is proposed in this paper to improve system stability and harmonic suppression. The proposed strategy integrates an enhanced state observer with a quasi-resonant harmonic suppressor to better observe and compensate for5 th and 7 th harmonic disturbances. Furthermore, a repetitive control-based disturbance observation loop is introduced to improve the estimation accuracy of periodic disturbances. The performance of the proposed control strategy is evaluated in terms of tracking performance, disturbance rejection capability, and robustness. Simulation results indicate that the proposed controller significantly outperforms conventional PID controllers and traditional ADRC methods, showing clear advantages in low-order harmonics suppression, dynamic response speed improvement,and system robustness enhancement. The effectiveness of the control strategy in suppressing the 6 k±1 th order harmonics in the three-phase currents is validated through a semi-physical experimental platform for the permanent magnet synchronous motor.
