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.  

Key words: Keywords：thruster configuration, fuel consumption, control allocation
