摘要

介绍了一类使用微机电速率陀螺组合、具有全稳定功能、且无天顶跟踪盲锥区的新型高精度三轴光电稳定跟踪装置的稳定机理。首先分析了该类装置中的坐标系及其相互之间的关系

然后运用多体力学的方法推导了该类装置的运动学方程

得出了三轴平台式速率稳定装置的数学模型。该模型表明

实现三轴全姿态稳定

不同的陀螺安装方法有不同的优缺点。研究了由于瞄准线稳定误差带来的图像相对运动和变形情况

分析了瞄准线稳定精度对图像稳定精度的影响。结果表明

两轴稳定装置绕轴线的旋转会造成比较大的图像稳定误差

而三轴稳定装置可以有效抑制绕轴旋转误差

从而达到较高的图像稳定精度。

Abstract

With whole stabilization ability

whole airspace tracking and no blind-zone

a high accuracy three-axis E-O stablilization and Tacking Devices(EOSTD) which uses a MEMS vlocity gyroscope as inertial feedback component was introduced. The coordinates in this device were analysized and the kinematic equation and the stabilization model were deduced based on the multi-body kinetic theory. The mathematical model indicates that different gyroscope installation methods can be used to realize three-axis attitude stabilization. Also the motion and distortion of image caused by the jitter of the Line-of Sight(LOS) were researched and the relationship between the LOS stabilization precision and the image stabilization precision was analyzed. The results show that two-axis EOSTD would cause large image stabilization error and three-axis EOSTD could restrain the image rotation around the LOS axis to reach a high stabilization precision.
