摘　　要：针对由多个细胞星构成的组合卫星的姿态控制问题,提出了一种包含控制力矩计算层与冗余力矩分配层的双层姿态控制方法。将细胞星间的冗余力矩分配问题转化为群体博弈的策略选择问题,综合考虑能量消耗、飞轮输出力矩裕度和飞轮角动量裕度设计收益函数,以力矩分配系数作为群体质量,以细胞星作为策略建立群体博弈模型。考虑群体演化中模仿和比较形成的不同演化策略,分别采用Smith动力学以及复制器动力学修订协议求解博弈的Nash均衡解,并利用有限制策略的群体博弈理论形成分布式冗余力矩分配方式,得到各个细胞星的控制策略。最后通过仿真实验验证了此分配方式的有效性。For the attitude control of combined satellites composed of multiple cellsats,a two-layer attitude control method including control torque calculation layer and redundant torque distribution layer is designed.The problem of redundant torque distribution is transformed into the strategy selection problem of population game.By setting a benefit function that comprehensively considers energy consumption,flywheel output torque margin and flywheel angular momentum margin,the population game model is established with torque distribution coefficient as the group mass and cell satellite as the strategy.Considering the different evolution strategies formed by imitation and comparison in group evolution,the Nash equilibrium of the game is solved by using group dynamics,and the distributed redundant torque distribution method is formed by using the group game theory with limited strategies.Finally,the effectiveness of this allocation method is verified by simulation experiments.
