Periodic and quasi-periodic orbits induced by optimal control in the hill three-body problem
摘要
Periodic and quasi-periodic orbits are fundamental structures in celestial mechanics and play a crucial role in trajectory design for multi-body systems and deep space missions. While conventional designs rely on natural equilibrium points, artificial equilibrium points enabled by continuous low-thrust propulsion offer greater flexibility and fuel-efficient trajectory design. This study formulates controlled orbital motion as a high-dimensional dynamical system governed by continuous optimal control and applies dynamical systems theory to analyze its stability and bifurcation properties. The results reveal families of new controlled orbits and associated dynamical structures, providing the design space for efficient and flexible trajectory planning in multi-body environments.
