摘要： 对追踪器逼近无控旋转目标器的轨迹和姿态六自由度控制问题进行了研究。基于适用于任意偏心率的航天器相对运动轨道和姿态动力学模型，对追踪器逼近无控旋转目标的参考轨迹和参考姿态进行了分析与设计，推导了一种用于六自由度逼近控制的自适应滑模控制器。通过仿真分析，证明了所设计的逼近参考轨迹和参考姿态的合理性，同时验证了自适应滑模控制器的有效性。

Abstract: The problem of trajectory and attitude control for a chaser to approach to an uncontrolled rotating target satellite is researched in this paper. Based on the orbit and attitude dynamics equations of two relative motion spacecrafts with arbitrary eccentrics, the reference trajectory and the attitude for a chaser to approach to an uncontrolled rotating target are analyzed and designed, and a kind of adaptive sliding mode controller is proposed for the six degree of freedom position and attitude control. The simulation results shown that the reference trajectory and attitude designed are reasonable, and the adaptive sliding mode controller is effective.

Key words: Spacecraft, Space rendezvous, Relative motion, Trajectory, Attitude, Adaptive sliding mode control
