地月低能轨道转移的混沌控制方法

针对航天器在混沌区域的滑行时间过长,提出一种低能地月轨道转移的混沌控制方法。首先通过地月圆形限制性三体问题(CRTBP)的庞加莱截面图,将混沌区域进行分层并分析其规律,再利用混沌轨道对初始状态高度敏感的特性,在尽可能减少运送时间的前提下实现地月低能轨道转移。该方法的优点是利用混沌区域的固有规律,不需要依靠周期轨道特性。仿真结果表明,本文提出方法仅需施加2~4次脉冲,明显缩短混沌区域的滑行时间,从而实现地月低能转移。

Chaos Control Method of Earth Moon Low Energy Orbit Transfer

A new chaos control method of Earth-Moon orbit transfer is proposed to reduce the transfer time of a spacecraft wandering in the chaotic region. Considering the circular restricted three-body problem (CRTBP), the chaotic region is divided into several layers according to the Poincaré section map, and the rules of each layer are analyzed. Besides, the properties that the chaotic orbit is highly sensitive to the initial conditions are fully utilized, and the chaotic orbits are constructed to meet the requirement of minimizing the transfer time. The proposed method takes advantage of the rules in the chaotic region, which is not necessary to rely on the location of the periodic orbits. Finally, the numerical results are provided to reveal that the transport time in the chaotic region can be significantly reduced with only 2-4 impulses.
