摘　　要：针对无向拓扑多航天器系统的分组姿态协同控制问题进行研究。采用修正罗德里格斯参数描述航天器的姿态,并基于一种包含姿态及其导数的辅助变量,提出了分布式的控制输入,将分组姿态协同控制问题转化为辅助变量的分组一致问题。结合代数图论和Lyapunov稳定性理论,证明了所提出的控制输入能够使多航天器系统渐近达到静态的分组姿态协同。仿真结果表明了控制输入的有效性,与现有研究对比,所提出的控制输入在控制效率上更具优势;在控制效果上更贴近实际工程应用需求。Multi-spacecraft system group attitude coordinated control with indirect topology was investigated.The attitude of spacecraft was described by Modified Rodrigues Parameters,and a distributed control input was proposed based on the auxiliary variable,which can turn the group attitude coordination problem into group consensus problem of the auxiliary variable.With algebraic graph theory and Lyapunov stability theory,it is proved that the control input proposed can lead the multi-spacecraft system to static group attitude coordination asymptotically.The effectiveness of the control input was verified by simulation result,and it is shown by comparison with the existing research that the control input has an advantage in control efficiency.At the same time,the control result of the control input is closer to realistic demand in engineering application.
