编队航天器多脉冲机动协同控制仿真
Coordinated Control System Simulation of Formation Spacecraft Multi-Impulsion Maneuver

针对航天器编队飞行协同机动任务，设计了一种基于一致性理论的编队航天器轨道机动协同最优控制律。采用适用于任意椭圆轨道的方程来描述编队航天器相对运动，考虑J2摄动项对编队航天器轨道运动的影响，针对Lambert问题，基于一阶一致性理论提出协同控制律，设计了多脉冲的轨道机动策略。采用遗传算法进行优化，结合机动过程中的编队构型保持，实现燃料最优的协同控制。仿真结果表明，该方法能够有效实现编队航天器的最优协同机动。
For the fast maneuver of spacecraft formation flight, an optimized cooperative control strategy based on the consensus algorithm is introduced. Considering J2 perturbation, relative motion between satellites is described by a new state transition matrix, appropriate for arbitrary elliptical orbits. Based on the Lambert problem, multi-impulsion orbital transfer strategy is proposed, controlled through single-order consensus algorithm. With formation maintained during orbital transfer, the minimum fuel-cost cooperative strategy is optimized via genetic algorithms (GA). Simulation results show that the consensus control strategy provided is effective and satisfying, especially fit for configuration maintenance during orbital transfer of the formation.
