摘要
研究悬浮轨道附近的编队飞行问题,推导了悬浮轨道附近的相对运动方程．由于编队太阳帆之间的距离与帆到太阳的距离的比值为小量,将相对运动方程在悬浮轨道附近线性化,得到了线性化方程．基于该线性化方程,考虑了悬浮轨道附近的几种编队控制方法,只需通过调节太阳帆的姿态来进行简单的控制．其中包括一种被动编队控制策略,该控制策略具有实现简单、稳定区域大的特点,具有很好的工程应用前景．最后基于非线性方程对每种编队策略进行了数值仿真验证,数值结果表明该控制方法能实现编队．
This paper investigates the formation flying around a displaced orbit. The equation for relative motion is derived. Since the displacement between two different solar sails is very small compared with the displacement from the sails to the sun, the equation of motion is linearized around the nominal displaced solar orbit to obtain a linear equation. Based on the linear equation, three formation control strategies are discussed, including the passive control strategy. This strategy has the advantages of simplicity and large stable region. Simulations based on the nonlinear equaiton are given. The results show that strategies can realize the formation around the displaced solar orbit.
