摘　　要：针对空间无线光通信中捕获、瞄准和跟踪(ATP)技术的粗跟踪系统对信标光斑实时准确跟踪需求,为项目进一步工作提供基础,搭建了无线光通信的粗跟踪模拟实验系统,介绍了实验所需硬件的相关参数及实验方案,基于模糊PID控制策略进行了不同速度下的一维模拟跟踪实验。结果表明,跟踪误差随着模拟仿真台的运动速度的增加而增大,但始终满足于粗、精跟踪嵌套精度需求。In order to track the beacon facular precisely in real time, a simulation system for coarse tracking with ATP technology for free-space optical communication is established. Relative parameters and experimental scheme are analyzed, and one-dirnentional tracking simulations are carried out under different speeds based on Fuzzy-PID control strategy. The experimental result shows that the tracking error increases with the increase of the working speed of the simulation platform, but it can satisfy the required precision of fine tracking system.
