Abstract: In the attitude control of micro nano satellite group, multiple satellites are required to cooperate with each other to quickly achieve the desired target attitude. At the same time, the energy consumption is required to be minimized. In this paper, a multi objective optimization model for attitude control of micro nano satellite group is proposed to simultaneously minimize the angle errors of satellite attitudes and the energy consumption. The elastic constraint method implemented in Matlab is used to solve the optimization problem. The Pareto frontier of multi objective optimization is obtained, and the corresponding satellite attitudes are given to realize the attitude maneuver control and the cooperative control of multiple micro nano satellites. Simulation results show that the multi objective optimization method used in this paper is effective in attitude maneuver control and cooperative control of micro nano satellite.
