摘　　要：为解决非合作空间目标机动、自旋、章动等动态特性对自主交会过程带来的困难和挑战,在某飞行器姿轨控一体化推进系统配置的基础上,充分考虑各类约束后构建标准的凸优化自主交会数学模型;着重分析了非合作目标动态特性对制导误差的影响,设计相应的修正策略;以原始对偶内点法作为核心求解器,设计了具备状态预测和更新能力的制导算法;数学仿真验算表明,该方法合理可行,克服了动态特性造成的接近轨迹偏差,良好地适应了非合作交会任务。Space autonomous rendezvous to a non-cooperative target is a key technology of an on-orbit operation mission or space attack and defense mission.Maneuvers of a non-cooperative target spacecraft brings many difficulties,such as avoiding,spin and nutation.A standard convex programming problem for the autonomous rendezvous based on a certain propulsion system under some necessary constraints is formulated in this paper.Then,the guidance errors which are caused by the non-cooperative target’s dynamic characteristics and elimination technique are analyzed.An advanced guidance method is proposed.The primal-dual interior point method is the core optimal algorithm of this method.Finally,several explicit simulations are carried out to confirm the feasibility and robustness of the present algorithm.
