提出了一种能考虑复杂摄动模型的卫星编队飞行相对绕飞控制策略,该策略仅需进行切向和法向控制,控制律不需要改变推力大小和方向,不需要进行卫星的姿态机动,适用范围广。对绕飞角、绕飞中心、绕飞基线等编队构形参数的控制精度高,对绕飞角的控制误差可达0.05°以下,绕飞挠率控制到0.001以下。此外,绕飞中心、绕飞角、绕飞基线、最小距离、最大距离均可稳定地保持,控制后编队构形稳定性好,有利于延长保持控制的周期,节约推进剂的消耗。该策略首次实现了对绕飞中心和绕飞挠率的控制。
This paper proposes a control strategy of relative orbiter formation of satellite formation flying considering complex perturbation model, which only needs tangential and normal control. The control law does not need to change the size and direction of thrust, and does not need attitude maneuver of satellite, Wide range of applications. The control precision of formation configuration parameters such as the angle of attack around the fly center, the fly center, and the fly-around base line is high, the control error around the angle of attack is up to 0.05 °, and the fly-by-roll ratio is controlled below 0.001. In addition, around the fly center, around the flying angle, around the fly-off baseline, the minimum distance, the maximum distance can be maintained steadily, control the formations formation stability, conducive to maintaining the control cycle, saving the consumption of propellants. For the first time, this strategy achieves control of the center of the fly-around and the fly-by-roll ratio.
