The invention relates to a method for synchronously tracking and controlling the position and attitude of a space rolling target. The method comprises the steps that a mathematical model describing the relative position movement of a spacecraft and the space rolling target is established; 2 the attitude movement equation of the rolling target is established; 3 a relative attitude movement model for tracking the spacecraft and the tumbling target is established; and 4 a fast sliding mode control method is designed based on the relative position movement model established in the first step and the relative attitude movement model established in the third step, and the tracking spacecraft can synchronously track and control the position and attitude of the rolling target. 本发明涉及一种空间翻滚目标位姿同步跟踪控制方法，第一步，建立描述追踪航天器与空间翻滚目标相对位置运动的数学模型；第二步，建立翻滚目标的姿态运动方程；第三步，建立追踪航天器与翻滚目标的相对姿态运动模型；第四步，根据第一步建立的相对位置运动模型和第三步建立的相对姿态运动模型，设计快速滑模控制方法，实现追踪航天器对翻滚目标的位姿同步跟踪控制。
