摘要：针对柔性涡簧振动和电力电子装置等引起机械弹性储能(MEES)系统机械侧谐波难以准确建模、多源谐波无法整体表征及统一抑制的问题,该文提出MEES用永磁同步电机多源谐波提取及统一抑制方法.首先,建立MEES系统数学模型,利用电机转速谐波对多源谐波进行整体表征;然后,提出融合奇异值差分的矩阵束算法,利用其对含噪实测转速数据进行处理以获取包含不同频率成分的多源谐波信息;最后,设计定子电流矢量定向下基于反推控制的多源谐波统一抑制算法,完成对不同频率成分谐波的同时抑制.仿真和实验结果表明,利用融合奇异值差分的矩阵束算法能快速、准确地识别转速信号中的多源谐波成分,统一抑制算法有效降低了多源谐波导致的电磁转矩脉动,改善了系统运行性能.
