摘要
微机械惯性仪表具有成本低、可靠性高、体积小、重量轻等优点，国际上已有许多报导［１］－［５］。我们研制了一种振动轮式微机械陀螺仪［６］。本文主要针对这种微机械陀螺仪的特性进行研究：设计和研究了陀螺的检测系统、检测轴固有频率补偿回路，推导出了此类陀螺检测输入角速度的灵敏度、开环和闭环传递函数、交流反馈控制提取同相分量和抑制正交分量的原理，以及闭环控制改善动态测量频带的方法。本文的最后给出了该陀螺原理样机的初步试验结果。
Micromechanical inertial instruments have great advantages of low ost,high reliability,small
size,lightweight,etc.There are many references discussed about this topic in the world .We
have designed a vibratory wheel rate gyro .The studies carried out in this paper are mainly
on the performance of this gyroscope.The detecting system of this gyro and the compensating
circuits of the detected axis's inherent frequency are designed and studied.The sensitivity,open
loop and close loop transfer functions in detecting the input angular rate are derived.The theory
of AC feedback control for extracting the inphase component and the orthogonal component from
original signal is presented,the method of using close loop control to improve the dynamic
measurement bandwidth is given,and at the end of this paper,the primary experiment results of
the prototype are shown.
