摘　　要：为了减小电机参数变化对电流谐波抑制效果的影响,提高谐波补偿电压的精度,提出了一种考虑参数变化的电流谐波抑制方法来抑制内置式永磁同步电机(IPMSM)控制系统中的电流谐波.在电流谐波抑制方法的基础上,引入遗忘因子递推最小二乘法(FFRLS)构建自适应电流谐波抑制环,通过FFRLS在线辨识IPMSM运行过程中的电机参数,并将参数变化的辨识结果引入到稳态谐波电压方程中,动态更新谐波补偿电压,从而减小了电机参数变化对谐波补偿电压产生的影响,提高了电流谐波抑制的效果.最后,仿真和实验结果验证了提出方法的正确性和有效性.In order to reduce the influence of motor parameters variation on the current harmonic suppression and improve the accuracy of harmonic compensation voltage,a current harmonic suppression method considering parameters variation is proposed to suppress the current harmonic for interior permanent magnet synchronous motors(IPMSM)control system in this paper.Based on the current harmonic suppression method,a forgetting factor recursive least square method(FFRLS)is introduced to build an adaptive current harmonic suppression loop.The FFRLS can identify the IPMSM parameters,and the identification results of parameters variation are introduced into the steady-state harmonic voltage equation to dynamically update the harmonic compensation voltage.Therefore,the influence of motor parameters variation on the harmonic compensation voltage generation is reduced,and the effect of current harmonic suppression is improved.Finally,the effectiveness of the proposed method is verified by the simulation and experimental results.
