AI总结：
本文提出了一种小型卫星六自由度控制的最优推力器配置方法，通过减少推力器数量仍能实现有效姿态控制。
摘要：
随着小型卫星（如立方星、纳星、皮星和飞星）在低地球轨道（LEO）中越来越多地用于特定应用，如成像、通信、数据存储和对接任务，对轨道维持和姿态控制的关注日益增加。一种常见的主动轨道控制方法是使用多个推力器，当这些推力器正确排列时，也可以生成所需姿态控制的扭矩。从24个推力器配置出发，本文提出了一组推力器配置（称为可行配置组），能够实现完整的六自由度（6-DOF）控制。进一步，在可行配置组中发现一组要求最小总推力以实现6-DOF指令的配置组。通过代表性的对接任务，对每组中的一个配置进行评估，其姿态控制性能得到验证，证明即使推力器数量减少，仍能实现足够的机动能力。
英文摘要：
With the growing deployment of small satellites (such as CubeSats, Nanosats, Picosats, and Femtosats) in Low Earth Orbit (LEO) for targeted applications like imaging, communication, data storage, and rendezvous-docking mission, there is increasing attention on orbit maintenance and attitude control. A common approach for active orbit control involves the use of multiple thrusters, which, when properly arranged, can also generate the required torque for attitude control. Starting from a 24-thruster configuration, this paper presents a set of thruster configurations (referred to as a viable configuration group) that enable full six degrees of freedom (6-DOF) control. Further, configuration group that requires minimum total thrust to achieve 6-DOF commands are found among the viable configuration group. One configuration from each of these groups is further evaluated for its attitude control performance through a representative rendezvous-docking mission, demonstrating that even with a reduced thruster count, sufficient maneuverability can be achieved.
