一种有源超低频速度传感器样机的设计
An Active Ultra-Low-Frequency Speed Sensor Prototype Design
摘要
Abstract
Based on magnetic vibration sensors,we designed a ultra-low frequency speed sensor based on active feedback control. Through a theoretical analysis on the designed sensor, the system transfer function and equipment parameter expression were obtained. Two prototypes were produced and tested. The experimental results proved that through reasonable feedback control, natural vibration frequency drops from 4 Hz to 0. 02 Hz, which greatly improves the low-frequency response of the sensor. Meanwhile, some problems, hoping to be solved in the future research, were enumerated too.关键词
