| 摘 要： | 对小推力轨道保持方法进行了研究。用快、慢变量控制器分别控制轨道要素的快慢变量,基于推导的经典轨道要素与2个推力方向角和最佳变轨位置的关系,给出了最优推力方向角的解析表达式。用Lyapunov反馈控制实现卫星轨道机动的轨道转移,并引入相位调整,实现了卫星的站位保持。仿真结果表明:基于Lyapunov的反馈控制可实现小推力轨道的转移和保持。

| Abstract: | The fast and slow variable controllers were used to control the fast and slow variable respectively. The function expression of the optimal thrust orientation angle was given out based on the relationship of the classic orbital elements with the two thrust angle and the optimal orbit changing position. The orbit transfer of the spacecraft orbit maneuver was realized by the Lyapunov feedback control, and the station keeping of the spacecraft was realized by adopting the phase adjusting. The simulation results showed that the orbit transfer and keeping with low thrust were be realized by the Lyapunov feedback control. |
