挠性陀螺转子正、反转监控技术研究

Monitor Technique of the Flex Gyrorotor Positive-Reverse Rotation Research

众所周知,对系统陀螺监控的方法有多种,近年来我们采用附加陀螺的方法对系统陀螺的漂移进行监控,而解决这一问题的关键在于监控陀螺正、反转技术实现的可行性。本文通过大量的试验,探索陀螺正、反转漂移变化的规律以及受环境因素影响后漂移特性的变化。试验结果表明:监控精度指标△C的稳定度已达到了0.04度/小时,有望在实际系统中应用。

As is known to all,there are many kinds of methods of moni- toring gyro drift.In recent years,we have utilized an additional gyro to monitor the system gyro drift,but the key to a solution of this problem is the feasibility of the monitor gyro positive and reverse rotation in fact.In this paper on the basis of a lot of experiments,we study the law of gyro positive and reverse rotation,the change of gyro drift with voltage and temperature.The results of experiments state clearly:the stability of monitoring index △C has reached 0.04°/ hr,this kind of monitor tech- nique will probably be used in the inertial navigation system.
