Abstract

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.

基于改进型无传感器反馈控制方法的电磁振动器振动谐波抑制技术

摘要为实现电磁振动器输出振动波形的低谐波失真，我们提出了一种基于改进的无传感器反馈控制方法的振动谐波抑制技术。在不改变原有驱动电路的前提下，利用驱动线圈的交流等效电阻获取高精度振动速度信息，进而建立简单可靠的速度反馈控制系统。通过研究不同关键参数值对系统的影响，我们实现了低频振动速度特征频率带的有效扩展，从而增强了速度反馈控制的谐波抑制能力。我们通过大量实验证明了所提方法的有效性，并与传统控制方法进行了比较。在 0.01-1.00 Hz 频率范围内，在不使用任何传感器的情况下，与开环控制相比，本研究提出的方法可将振动波形的谐波畸变降低约 40%，与传统的无传感器反馈控制方法相比，可降低约 20%。
