摘　　要：首先进行了三轴稳定卫星观测问题的背景分析,建立了相应的数学模型,进而提出了一种基于遗传算法和模拟退火算法的混合遗传算法,通过多个仿真算例验证了其有效性,并与模拟退火算法的运算结果进行了比较分析,结果表明其运算速度和全局寻优能力均优于单独使用模拟退火算法。The analysis of the background of the observation problem about the three--axis stabilized satellites was given and a mathematical model of this problem was established. Then based on genetic algorithm and simulated annealing algorithm, a combined genetic algorithm for this problem was presented Through several cases, the feasibility and correctness of the new algorithm were proved. In addition, compared with simulated annealing algorithm, this proposed algorithm demonstrates that both the operation speed and the global optimization ability are better.
