| 摘 要： | 摘要： 为实现精准的交会对接需要同时进行相对位置与相对姿态的六自由度控制.在控制指令一定的情况下，不同的推力器配置以及不同的控制分配算法会带来不同的推进剂消耗.实际任务中，可以从时间和空间上对控制指令进行划分，即控制指令在一段时间内集中在一定的空间区域内.本文提出发动机配置区域平均燃料消耗的度量指标，针对三维和六维控制任务给出区域平均燃料消耗的计算方法，进而提出对推力器配置阵的优化思路，对于完善控制指令分配和推力器配置设计与优化有重要的意义.

| Abstract: | Abstract：To realize the high accuracy rendezvous and docking, the 6 degree orbit and attitude control is needed. For the same control command sequence, different thruster configurations and different control allocation algorithms lead to different fuel consumptions. As the control command sequence can be divided by time and space region, the regional average fuel consumption is proposed. The computing method of the regional average fuel consumption is given for both the 3 degree and the 6 degree control tasks. The optimal design method of the thruster configuration is suggested, which has important significance for thruster configuration design and control allocation. |
