Asymptotic Tracking

Author: Tianjiang Shuo

Definition

A libration point orbit control strategy that designs a controller to drive the spacecraft state to converge asymptotically to a nominal orbit over time. Unlike the Floquet mode which targets unstable components, asymptotic tracking uses the full nominal orbit as the target without separating stable and unstable modes. Howell et al. investigated asymptotic tracking for Halo orbits using linear control methods.

Application Value

This concept has practical applications in cislunar space science and engineering. Related research supports the planning, implementation, and operations of cislunar missions, forming an integral part of the knowledge system in this field.
