Current methods which stabilize unstable Earth-Moon cyclers are only effective for a few orbits.A chaos control method for unstable Earth-Moon cyclers in the circular restricted three-body problem is proposed in this paper.First,candidate fixed points and their corresponding poincaré map are selected on a cycler.Second,the projection point of the cycler is moved to the stable direction of the fixed point by chaos control method on the poincaré map.Third,the proportion of the deviation distance between the target point and the projected point to the fixed point after the cycler is controlled.Finally,the poincaré map is determined according to the selected fixed point,the control pulse amount is calculated,and the Earth-Moon cycler is stabilized.The numerical results are provided to reveal that the proposed method is suitable for various types of Earth-Moon cyclers,which saves at least 66%energy consumption compared to the existing methods,and can stabilize the cycler for a long time.
