| 摘 要： | 基于T H方程推导了椭圆参考轨道编队飞行的周期性条件,讨论了椭圆参考轨道卫星编队飞行的典型模态。该模态是圆形参考轨道空间圆形模态的推广。论述了二阶带谐项(J2项)摄动对编队飞行构型保持的影响,基于相平面法提出了一种编队飞行构型保持控制方法。该控制方法不是消极的抵消干扰的影响,而是积极的利用干扰的作用达到节约燃料并精确保持构型的目的。仿真表明,采用该控制方法可对椭圆参考轨道卫星编队构型进行有效的保持。

| Abstract: | The periodicity conditions of spacecraft formation flying in eccentric orbits were derived from the Tschauner-Hempel equation. The representative mode of spacecraft formation flying in eccentric orbits was given. This mode is generalized from space circular configuration of spacecraft formation flying in circular orbits. The influence of quadratic zonal harmonic term (J\-2) perturbation on flying configuration was studied. The formation-keeping control algorithm was put forward. In order to economize fuel, this control algorithm not passively counteracts the influence of perturbation, but actively makes use of perturbation. Simulation results show that this control algorithm has nice performance on formation keeping. |
