摘要
针对J2摄动和大气摄动导致低轨编队卫星构型破坏的情况,基于高斯摄动方程给出了以平均轨道根数为被控制量的脉冲控制模型。利用法向脉冲调整轨道倾角和升交点赤经偏差,在轨道上2个位置施加径向和切向脉冲调整其余轨道根数偏差从而修正卫星编队构形。最后通过数值仿真验证了算法的简单性、有效性。
Based on Gauss perturbation,impulsive control model for formation keeping is put forward with regard to the problem that LEO satellites formation could be destroyed under J2 perturbation and atmospheric drag perturbation.In order to correct errors of formation keeping,firstly,the inclination and longitude ascending node is adjusted by exerting an impulsive control effort along the normal direction.Then,the other elements errors are amended by exerting impulsive control efforts from two positions along tangent and radial directions simultaneously.Finally,the simplicity and effectiveness of the impulsive control algorithm is verified by mathematical simulation results.
