摘　　要：微型航天器在交会对接、在轨服务等太空任务中所起的作用日益凸现,高精度地保证近旁操作的完成是实现其功能的关键。利用两套五自由度卫星模拟器,在一个面积为3m×4m的大理石试验台上,搭建了一套微型航天器近旁操作地面仿真验证系统。针对典型的近旁操作任务,进行了仿真实验。利用边缘检测等图像处理技术获得目标的相对位置信息,利用模糊控制方法实现了从航天器对主航天器的自主探测、自主接近和近旁保持。实验结果表明,仿真系统能够对近旁操作任务进行功能及原理的仿真验证,为进一步的工作奠定了基础。The micro-satellite plays an increasingly important role in many space missions like rendezvous ＆ docking or on-orbit servicing, and the high precision control of proximity operations is the key technology within these tasks. With two five degree-of-freedom micro-satellite models and a 3m×4m smooth granite table, a ground simulation system for validation of micro-satellite proximity operations was built up. A series of experiments were carried out to validate the control method for typical proximity operations. With the host spacecraft status data calculated by some useful image processing technologies such as edge detection, the follower spacecraft could detect the host spacecraft and approach to it autonomously under the control of a fuzzy controller. The controller is also suitable for station keeping. Experimental results reveal that the simulation system can validate the functionality and principals of the proximity operations and these experiences are meaningful for future work.
