摘要
在实验中发现.微石英音叉陀螺在自激振荡驱动回路中的等效阻抗随驱动电压幅值的变化而变化,具有不稳定性。在阐述微石英音叉陀螺基本工作原理及其模拟驱动电路设计基本原则的基础上,研究了微石英音叉陀螺等效阻抗的不稳定性对其模拟驱动电路的影响,从一个侧面说明了现有实用的微石英音叉陀螺模拟驱动电路大多为方渡驱动电路的原因,以及模拟正弦波驱动电路的不可行性。
Rate Sensor＇ s （QRS） equivalent impedance in self-excited driving circuit is instability, but change with the amplitude of drive signal, which was discovered in experimentation. Based on working mechanics of QRS and the principle of how to design analog drive circuit for QRS was expatiated, the effects of the instability of QRS＇s equivalent impedance in the analog drive circuit was studied, and had explained why most of QRS＇s analog drive circuits are square wave circuit, as so as sine wave drive circuit＇s infeasibility partly.
