Using Reinforcement Learning to Design a Low-Thrust Approach into a Periodic Orbit in a Multi-Body System

, 2020
Exploring multi-body systems with low-thrust-enabled small satellites opens up a new frontier of scientific opportunities. However, the limited control authority of these spacecraft introduces significant challenges during trajectory and maneuver design.

Desynchronization by periodic orbits

Physical Review E, 1995
Synchronous chaotic behavior is often interrupted by bursts of desynchronized behavior. We investigate the role of unstable periodic orbits in bursting events and show that they serve as sources of local transverse instability within a synchronous chaotic attractor. Analysis of bursts in both model and experimental studies of two coupled R\"ossler-like

Multiple bifurcations in the periodic orbit around Eros

, 2016
We investigate the multiple bifurcations in periodic orbit families in the potential field of a highly irregular-shaped celestial body. Topological cases of periodic orbits and four kinds of basic bifurcations in periodic orbit families are studied ...
