考虑燃料均衡的卫星编队队形重构技术

Fuel-Equalized Satellite Formation Reconfiguration Technique

在卫星编队队形重构过程中,如何在实现编队整体燃料消耗较少的同时使得各子卫星燃料消耗均衡,能够有效地提高卫星编队整体的寿命。提出了一种基于虚拟中心位置可变的卫星编队队形重构新方法。该方法以虚拟中心位置为寻优变量,以首末脉冲时刻可优化的双脉冲规划作为单星轨道机动策略,将编队队形重构问题转化为混合0-1数学规划问题。仿真结果表明,该优化算法在实现整体燃料次优的同时,兼顾了各星当前的燃料剩余水平,实现了各子卫星的燃料均衡。

During the process of satellite formation reconfiguration,it is important to make each satellite fuel consumption equalized while the total fuel consumption of all satellites are as little as possible,thus increasing the life time of the formation effectively.A new method of the satellite formation reconfiguration is proposed based on the virtual reference center to be changeable.In this method,the virtual center of the formation is considered to be an optimized variable,double impulse programming method is adopted as the single satellite orbit maneuver strategy that acting times of two impulses can be optimized,and the problem of formation reconfiguration is transformed into a mixed 0-1 mathematic programming problem.Simulation results manifest that while the total fuel consumption of the formation is suboptimal,the new method can make each satellite fuel consumption equalized in consideration of the present residual fuel of each satellite.
