使用位置环的惯性稳定系统中陀螺漂移误差软件修正方法

Software for correcting gyro drift error in inertial stabilization system

针对使用位置环的惯性稳定系统中存在因陀螺固有温度漂移特性引起的系统跟随位置误差,首先提出一种软件修正方法,给出此软件修正方法的理论基础及软件修正的具体实现过程,最后对此修正方法进行了实验验证。实验结果表明:在没有振动的情况下,修正程序能将漂移完全校正,效果良好;在存在振动的情况下,修正程序也能较好地校正漂移,但校正后存在1个或2个码值的误差。

A software correction method is proposed to reduce the tracking position error caused by the gyro temperature excursion in inertial stabilization systems with position loop. The theoretical foundation of the software correction method and the implementation process of the software correction are presented. The verification experiment for the correction method was carried out. The experiment result shows that the correction program can completely correct the excursion in the case of no vibration, and can still correct the excursion in the case of vibration, but with a code error of 1-2. inertial stabilization system; gyro temperature excursion software correction; position loop
