Halo Orbit Maintenance around L1 Point of the Sun-Earth System Using Optimal Control and Lyapunov Stability Theory

Trajectory optimization of space vehicle in rendezvous proximity operation with evolutionary feasibility conserving techniques

“…Successful space transportation is a fundamental goal in many space scenarios as it has direct effects on various space missions, such as spacecraft guidance and tracking (Zhang et al, 2020), rendezvous, docking, on-orbit refueling (Zhu et al, 2020), and orbital maintenance (Ramteke and Kumar, 2022). In such type of missions, the overall process of relative spacecraft maneuvering lies in transferring the chaser spacecraft, traveling in its initial trajectory, to a distance with acceptable relative velocity close to the chief spacecraft.…”
