动载体光电系统自主跟瞄稳定控制方法

摘要

In order to improve line of sight (LOS) stabilization precision and reduce tracking error caused by the time - delay of video conversion and target detection, this paper presents a method of moving carrier electro - optical equipment's independent aiming & tracking stabilized control. The method realizes the line of autonomous stability by using the swing disturbance of two orthogonal installed rate gyro sensitive carrier' s moving, and use a technique of double servo loop with frontback which can reduce the dead - zone. The Max of LOS stabilization precision is achieved lmrad and the Max of tracking error is less than 0. 3mrad in the experiment which use a two - axis vibrate turntable to simulate moving carrier.%针对动载体的摇摆扰动对光电系统瞄准线稳定的影响,以及视频转换和目标提取滞后等造成的跟踪精度低等问题,提出了利用两个正交安装的速率陀螺敏感载体摇摆扰动的原理,实现动载体光电系统瞄准线的自主稳定;同时采用一种带前馈的分段线性双环控制方法,实现目标的高精度自动跟踪;在模拟动载体上的实验结果表明,瞄准线稳定精度最大值优于1 mrad,跟踪精度优于0.3 mrad,控制方法可适用于动载体光电系统的自主瞄准稳定和跟踪.
