非合作目标编队飞行耦合动力学建模与六自由度控制

Modeling and Six-Degree-of-Freedom Control for Non-cooperative Satellite Formation Flying

研究了非合作目标编队飞行的相对轨道和相对姿态运动,分析了非合作目标编队飞行的相对位置运动和相对姿态运动的耦合关系;建立了非合作目标编队飞行的六自由度动力学模型;设计了基于指数趋近律滑模控制方法的控制器;并证明了该系统的稳定性。仿真结果验证了六自由度控制的有效性。

The relative position and the relative attitude motion of non-cooperative satellite formation flying are studied. The coupled relation of the relative position and the relative attitude are considered. A coupled six-degree-of-freedom model for non-cooperative satellite formation flying is established. A sliding mode controller based on the exponent reaching law is designed. The stability of the control system for the satellite formation flying is proved. Simulation results verify the effectiveness of the six-degreeof-freedom controller.
