基于迹向控制量的编队星群相位控制

为了得到控制量与控制时机对相位改变的直观公式,基于Hill方程以及迹向控制的约束条件,定性分析共面绕飞编队中控制量、控制时机与编队卫星相位之间的关系,分析结果表明:当需要改变的相位角小于90°时,可实现最省燃料的控制;当需要改变的相位角大于90°时,可进行趋于最小控制量的控制;当在相对运动椭圆上下点实施控制时,相位无变化.

Formation Phase Control Based on the along-Track Control Strategy

In terms of the engineering constraints, orbital maneuvering along the track is relatively easy to achieve. The relations among the quantity of control, the time of control and the phase are studied,that are based on the constrains of Hill equations and the along-track control for the eoplanar flying-around formation. The analytical results demonstrate that the minimum fuel consumption can be realized when the phase angle needing to change is less than 90°. Conversely, the minimum quantity of control can be ap- proached when the phase angle needing to change is larger than 90°. And further, it is found that the phase remains unchanged when the control is carried out at the up and down points of the relative motion ellipse.
