为了实现舰载激光武器在复杂作战环境中对目标的精确毁伤,提出一种基于快速反射镜的粗精复合稳定平台,用以控制激光光束的稳定精度。首先,介绍了系统组成及工作原理,设计了压电陶瓷驱动的全柔性精级快速反射镜,并且分析了该快速反射镜的性能特点。然后,设计了粗精复合控制系统,在此基础上探讨了粗精复合稳定平台各组成单元之间的相互影响因素。最后,通过理论计算推导了粗精复合控制系统的误差传递函数,并搭建了实验平台,进行了稳定精度测试实验。实验结果表明:在四级海况摇摆扰动条件下,相较于传统粗级稳定平台,方位复合平台的稳定精度从191. 6μrad提高到6. 7μrad,提高了约27. 6倍,俯仰复合平台的稳定精度从121. 3μrad提高到4. 9μrad,提高了约23. 8倍;在各种外界摇摆扰动下,粗精复合平台对激光光束的稳定控制精度均≤10μrad。满足了舰载激光武器平台对激光光束高精度稳定控制的作战需求。
