摘要
基于Hill方程分析了编队卫星队形设计中对初始参数确定的约束条件。用系统灵敏度理论分析了系统状态对初始参数摄动的灵敏度,获得了各初始参数摄动对构型变化的影响。仿真结果表明:初始参数中星地方向的位置摄动和航迹方向的速度摄动可导致编队队形迅速发散,而其他参数的影响较小。
The limitation in determination the initial parameters for the design of formation flying satellite was studied based on Hill equation in this paper.The sensitivity of the system state to the initial parameter perturbation was analyzed by the system sensitivity theory.The effect of each parameter perturbation on the formation was gained.The simulation results showed that the position perturbation in satellite-earth direction and the velocity perturbation in track direction were the two most important factor...
