| 摘 要： | 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。

| Abstract: | 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-zo... |
