Heuristic optimization for transfer trajectory to cis-lunar liberation point periodic orbit
The transfer strategies for multi-objective missions around the Earth-Moon Lagrange points are studied and a two-impulse transfer strategy that allows spacecraft to move between near-rectilinear halo orbits and distant retrograde orbits is designed. Firstly,the spacecraft's orbital dynamics model is established in the synodic frame. Then,the overall design of the transfer strategy is implemented,the relevant optimization variables are analyzed,the objective function and constraints are determined,and the transfer strategy design problem is transfered into a trajectory optimization problem. Furthermore,the feasibility of genetic algorithms and particle swarm optimization algorithms for this specific problem is verified for solving the transfer trajectory. A numerical method is presented through this research by applying genetic and particle swarm optimization algorithms to transfer strategies design of halo orbits,which focuses on recent interest in near-rectilinear halo orbits and distant retrograde orbits. The proposed optimization method has ability of effectively resolving the orbital transfer design problem without prior information and can be applied to various transfer scenarios.
