摘　　要：在微纳卫星群姿态控制中,要求多个卫星相互协同,能够快速达到期望的目标姿态,同时要求能耗最小.本文提出微纳卫星群姿态控制的多目标优化模型,以同时优化卫星姿态的角度误差和降低能耗2个性能指标函数.基于MATLAB用弹性约束法求解该优化问题,得到了多目标优化的帕累托前沿,并给出了其相应的卫星姿态,实现了多个微纳卫星姿态机动控制和协同控制.仿真结果表明本文运用的多目标优化方法在微纳卫星姿态机动控制和协同控制中是有效的.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.
