摘　　要：传统激光通信受到强电磁信号干扰时,导致电学引导机制失灵,初始指向将无法建立。为了解决强电磁干扰导致无法正常激光通信的问题,提出了一种结合伺服控制技术的全光捕获的控制技术。该方法对于全光引导光学模型进行解析研究,进而得出全光引导跟踪数学模型,在此基础上加入伺服控制技术,通过对高斯—赛德尔迭代算法的融合改进研究,以控制两个独立激光通信端机的快速捕获,精准指向与跟踪。实验结果表明,设计的捕获方案能进行全周90°/s的方位扫描,并55 s内完成俯仰20°的捕获。使激光通信在静默条件下快速建链有广阔的应用前景。When traditional laser communication is interfered by strong electromagnetic interference,it leads to the failure of electrical auxiliary guidance methods,and the initial pointing cannot be established.In order to solve the problem of abnormal laser communication due to strong electromagnetic interference,a control technology combining servo control technology for all optical capture is proposed.The method is an analytical study of the optical model of all optical guidance,which leads to the all-optical guidance tracking mathematical model,based on which servo control technology is added to improve the fusion of the Gauss Seidel Method algorithm,so as to control the rapid capture,precise pointing and tracking of two independent laser communication terminals.The experimental results show that the designed capture scheme can perform azimuth scanning at 90°/s throughout the entire cycle and complete capture at an elevation of 20°within 55 seconds,which makes the laser communication has broad application prospects for rapid chain building under silent conditions.
