研究了接近和跟踪同时存在姿态翻滚和轨道机动的非合作目标轨道姿态6-DOF联合控制问题。综合视线坐标系下相对运动动力学模型和追踪航天器姿态动力学模型，建立姿轨联合动力学模型。由于系统模型存在很强的非线性，所以对系统模型先进行预处理，将其转化成利于控制器设计的形式，采用Lyapunov最小-最大方法对同时存在姿态翻滚和轨道机动的非合作目标设计了自主接近和随动跟踪控制律。通过仿真验证了模型和控制方法的有效性。

A 6-DOF coupled translational and attitude dynamics model of a non-cooperative target with tumbling and orbital maneuver simultaneously is designed in this paper .On the basis of the relative motion model and the chaser's attitude dynamics described in the line-of-sight coordinate frame , the coupled translational and attitude dy-namics model is established .Because of the nonlinearity , pretreatment of the model should be considered first in order to transform the model into another form which is easier to derive;moreover , the control laws for approaching and tracking the target with tumbling and orbital maneuver are derived using the Lyapunov min-max approach .The simulation results and their analysis validate preliminarily the feasibility of our model and control laws .
