Abstract

A hi-speed rotation angular rate sensor based on an electromagnetic induction signal is proposed to provide a possibility of wide range measurement of high angular rates. An angular rate sensor is designed that works on the principle of electromagnetism (EM) induction. In addition to a zero-phase detection technique, this sensor uses the feedback principle of magnetic induction coils in response to a rotating magnetic field. It solves the challenge of designing an angular rate sensor that is suitable for both low and high rotating rates. The sensor was examined for angular rate measurement accuracy in simulation tests using a rotary table. The results show that it is capable of measuring angular rates ranging from 1 rps to 100 rps, with an error within 1.8‰ of the full scale (FS). The proposed sensor is suitable to measurement applications where the rotation angular rate is widely varied, and it contributes to design technology advancements of real-time sensors measuring angular acceleration, angular rate, and angular displacement of hi-speed rotary objects.

摘要

提出了一种基于电磁感应信号的高速旋转角速度传感器,为高角速度的宽范围测量提供了可能。设计了一种基于电磁感应原理工作的角速度传感器。除了零相位检测技术外,该传感器利用磁感应线圈响应旋转磁场的反馈原理。它解决了设计一种适用于低转速和高转速的角速度传感器的挑战。在使用转台的模拟测试中对该传感器的角速度测量精度进行了检验。结果表明,它能够测量1转每秒至100转每秒的角速度,满量程误差在1.8‰以内。所提出的传感器适用于旋转角速度变化范围很广的测量应用,并且有助于测量高速旋转物体的角加速度、角速度和角位移的实时传感器的设计技术进步。
