陀螺仪随机漂移的测取和数学模型的确立

Measurement of Random Drift of Gyro and Establishment of Mathematical Model

导弹控制系统中,陀螺精度是系统精度的重要指标之一,而陀螺仪随机漂移是影响陀螺精度的重要误差源,因而研究陀螺仪随机漂移对提高陀螺精度有着重要意义。本文在统计分析的基础上提出了用固定方位力矩反馈法测取陀螺仪的随机漂移,并简述了利用平稳时间法建立其数学模型的过程,对研究陀螺仪随机漂移具有重要的参考价值。

The precision of gyro is one of the most important points to decide precision of missile control system and it is mostly effected by the gyro random drift.On basis of statistics analysis, the fixed-azimuths-moment feedback method for measurement of random drift is put forward in the paper, and the mathematical model is established by means of stabilization time method, with greatreference to study of gyro random drift.
