To realize low harmonic distortion of the vibration waveform output from electromagnetic vibrators, we propose a vibration harmonic suppression technology based on an improved sensorless feedback control method. Without changing the original driving circuit, the alternating current (AC) equivalent resistance of the driving coil is used to obtain high-precision vibration velocity information, and then a simple and reliable velocity feedback control system is established. Through the study of the effect of different values of key parameters on the system, we have achieved an effective expansion of the velocity characteristic frequency band of low-frequency vibration, resulting in an enhanced harmonic suppression capability of velocity feedback control. We present extensive experiments to prove the effectiveness of the proposed method and make comparisons with conventional control methods. In the frequency range of 0.01‍–1.00 Hz, without using any sensors, the method proposed in this study can reduce the harmonic distortion of the vibration waveform by about 40% compared to open-loop control and by about 20% compared to a conventional sensorless feedback control method.


摘要:为实现电磁振动器低谐波失真振动波形输出,提出一种基于改进无传感器反馈控制方法的电磁振动器振动谐波抑制技术。在不改变原驱动电路的情况下,利用驱动线圈的交流等效电阻获得高精度的振动速度信息,建立简单可靠的无传感器速度反馈控制系统。通过研究不同关键参数值对系统的影响,有效扩展了低频振动速度特性频带,增强了速度反馈控制的谐波抑制能力。进行了大量实验来证明所提出的方法的有效性,并与传统的控制方法进行比较。在0.01 Hz至1.00 Hz的频率范围内开展对比实验,实验结果表明,所提出的方法与开环控制相比可以将振动波形的谐波失真降低约40%,与传统的无传感器反馈控制方法相比可以将谐波失真降低20%。
