小卫星围绕空间站飞行动力学和控制研究

A Study on Dynamics and Control of Small Satellite Flying Around Space Station

研究微小卫星围绕空间站飞行， 监视空间站运行和外观状态， 减少航天员舱外活动。这是小卫星一种新的应用概念。文章主要研究绕飞轨道动力学和稳定性， 以及在有摄动情况下保持绕飞轨道的控制策略。这种控制策略所消耗燃料非常少， 根据仿真实验结果， 绕飞卫星飞行一个月消耗的燃料可产生速度增量约为３～４ｍ ／ｓ。

With a small satellite flying around the space station, the operation and exterior state of the space station can be monitored,and the times of the astronaut's extravehicular activity are reduced.This is a new concept about the applications of the small satellite. With low consumption,the small satellite can fly around for long time.Mainly,the stability of flying around orbit is discussed and the control stratagem of overcoming the perturbation is presented.Flying around for one month consumes only 3～4m/s velocity increment .
