一种高精度的抖动偏频控制方法

A Control Method to Keep Dither Bias Stable

在激光陀螺的抖动控制中， 用作抖动幅度检测的ＰＺＴ 的灵敏度会随温度变化， 从而造成偏频失稳。本文提出了用计算机稳定偏频的方法， 设计了一种新型抖动控制器。实验表明： 该控制器能够较为精确地保持偏频的稳定。

During the performance of dithered ring laser gyros, bias level will change when the sensitivity of PZT used in measuring dither amplitude changes. A dither control method using a computer to keep bias stable is presented, and a new controller is developed. It is proved that this dither controller can keep bias stable.
