摘　　要：针对空间翻滚目标相对绕飞问题,采用基于旋量、对偶四元数的方法建立了相对动力学模型。以在轨翻滚航天器作为任务对象进行了相对绕飞的对偶双环滑模控制器设计,不仅保证了追踪航天器相对距离的稳定,还使其姿态能够与翻滚目标保持时刻同步。数值仿真验证了控制器的有效性。In view of relatively flying around a tumbling target problem,both dual quaternion and screw methods are applied to the relative dynamic model and a dual quaternion’s double-loop sliding mode controller is designed for a chaser craft to execute the task.Not only the distance between chaser and target space craft are stabilized,but also the posture of them kept the same.Numerical simulations test the effectiveness of the controller established.
