卫星伴随飞行的最优控制策略研究

伴随飞行技术在卫星编队、相互观测等活动中具有重要应用。为实现卫星对同一轨道面内,相对距离较远的近圆轨道目标飞行器形成相对椭圆伴飞,本文按照燃料最优原则,利用Hill方程推导得到稳态椭圆伴随飞行条件。以此为依据计算控制量,结合工程实际,对控制量进行线性规划,在规定时间完成半长轴、偏心率及两飞行器相对相位兼顾调整,最大程度节省燃料,实现对目标飞行器伴飞。

Design of Fuel-optimizing for Companion-flying Satelite

Companion-flying is essential for formation-flying, mutual observation and so on. To accomplish the companion-flying of co-orbit satellites, a new fuel-optimizing method of computing control which is based on the stability criteria of companion-flying is proposed. The control is determined by linear-programming in project. The co-orbit companion-flying is realized by controlling the orbit parameters a,e and relative-phase of two satellites.
