为了减少低能地月轨道转移时航天器在混沌区域的滑行时间,提出一种混沌多步控制方法.利用地月圆形限制性三体问题下航天器轨迹的运行规律和混沌轨道对初始状态高度敏感的特性,通过自适应粒子群优化算法计算出混沌控制每一步的最优扰动,进而实施多步控制实现地月低能轨道转移.该方法不需要依靠周期轨道和随机大量搜索,能够有效地实现地月低能轨道转移,并在耗费能量很小的前提下显著地缩短航天器在混沌区域的滑行时间.最后,数值仿真结果验证了所提出算法的正确性和有效性.%A multi-step control of chaos method is proposed in this paper to reduce the flight time in the chaotic re-gion of Earth-Moon low-energy orbit transfer. According to the motion regularity and the fact that the chaos orbit is highly sensitive to the initial conditions in the circular restricted three-body system,the optimal perturbation of cha-os control at each step is calculated by the adaptive particle swarm optimization algorithm,and then the low-energy earth-moon orbit transfer trajectory is obtained. This proposed method can efficiently construct the Earth-Moon low-energy orbit transfer trajectory without the relying on the periodic orbits and the requirement of random search,and the corresponding flight time in chaotic motion can be significantly reduced. Finally,numerical simulations are pro-vided to demonstrate the correctness and efficiency of this proposed method.
