基于视线制导的共面航天器自主交会控制研究

研究了基于视线制导的共面航天器自主交会控制.为便于设计适用于自主交会的控制方法,首先建立了视线坐标系相对运动方程,然后基于相对测量信息分别设计了纵向和法向控制器.纵向控制器是基于零控脱靶量算法所设计的一种新的自适应控制方法,完成交会速度和位置控制;法向控制器是一种姿态约束PI型比例导引,实现交会视线角的控制.所设计的控制器对不同初始交会条件具有良好的适应性.对圆和椭圆轨道交会仿真结果证明了该控制方法是有效可行的.

Control Strategies for Coplanar Autonomous Rendezvous Based on Line-of-sight Guidance

The control strategies based on line-of-sight(LOS) guidance for coplanar autonomous rendezvous were presented.The relative equations described in the local orbital frame were transformed into LOS frame.In the LOS frame,the rendezvous controllers along LOS and perpendicularly to LOS directions were designed respectively.To meet the requirements of relative positions and velocities in the rendezvous,a new adaptive controller in the LOS direction based on zero-effort-miss(ZEM) was designed.Then,a modified prop...
