针对柔性涡簧振动和电力电子装置等引起机械弹性储能 (mechanical elastic energy storage, 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,本文提出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;之后,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。

Abstract：

The vibration of flexible spring and power electronic equipment can cause multi-source harmonics in mechanical elastic energy storage (MEES) system. To solve the problems that mechanical side harmonics are difficult to be accurately modelled and the multi-source harmonics cannot be characterized and suppressed uniformly in the MEES system, a multi-source harmonics extraction and unified suppression method of permanent magnet synchronous motor (PMSM) is proposed for MEES system. Firstly, in allusion to the issues of overall characterization of multi-source harmonics, the speed and electromagnetic torque of PMSM are used as a bridge, and the characterization of multi-source harmonics is wholly modelled by using the motor speed harmonics. The expression of the relationship between multi-source harmonics and motor speed harmonics is derived from the motor rotor equation of motion, and the overall characterization of mechanical side harmonics and electrical side harmonics is realized. Then, in terms of multi-source harmonics information extraction for MEES systems, considering the existence of high and low frequency harmonic signal components in MEES system and the characteristic of low signal-to-noise ratio, a matrix pencil algorithm combined with singular value difference is proposed. The matrix called as Hankel is constructed by using the measured rotor speed containing noise. Subsequently, the singular value difference algorithm is utilized to find out the energy mutation point, and determine the maximum number of modes of the multi-source harmonic signals. Then, the multi-source harmonics information including different frequency components can be extracted accurately. Finally, to deal with the problem of multi-source harmonics suppression, based on the magnetic coenergy model of electromagnetic torque of PMSM and backstepping control, a unified suppression algorithm of multi-source harmonics under stator current vector orientation is designed to suppress the harmonics of different frequencies simultaneously.
To verify the control performance of multi-source harmonics suppression controller, simulations and prototype system test experiments are conducted, respectively. Simulation results show that the maximum error of high frequency harmonics information extracted is about 1%, and the maximum error of low frequency harmonics information extracted is about 5% by using the matrix pencil algorithm combined with singular value difference. The multi-source harmonics suppression algorithm reduces the low frequency harmonics content from 4% to 0.35% and the 6th harmonic content from 10.2% to 1%, which proves that the proposed algorithm has high accuracy of information identification and can satisfy the various needs of engineering applications.
The test experiments results of the prototype system show that, as the proposed controller is put into the MEES system, the angle $\theta_{\mathrm{L}}$. between the D-axis and the d-axis is stabilized near 90 degrees, and the static error is extremely small. In addition, the waveform of fundamental current vector amplitude i_s0 is smooth and there is virtually no fluctuations. The motor speed quickly converges to the reference with very small fluctuations when the system is running steadily, and the peak-to-peak value of torque pulsation ΔT does not exceed 0.1 N·m. It indicates that the designed controller can respond to the sudden change of motor speed quickly, and has good dynamic performance and stability. Also, the fluctuation of operating parameters is small. The practical operational performance of the MEES system has been dramatically improved.
