Orbital Station-Keeping in the Earth-Moon System via Nonlinear Backstepping
António Nunes, Pedro Batista, Sérgio Brás
A nonlinear orbital station-keeping solution for the circular and elliptic versions of the Earth-Moon Restricted Three-Body Problem (R3BP) is developed via a backstepping technique…

A Floquet Mode LQR for Orbital Station-Keeping in Cislunar Space
António Nunes, Sérgio Brás, Pedro Batista
A linear optimal control law for orbital station-keeping in the Earth-Moon Restricted Three Body Problem (R3BP) is developed via Linear Quadratic Regulator (LQR) theory. First, the…

Nonlinear backstepping with saturation for low-thrust station-keeping of libration point orbits
António Nunes, Sérgio Brás, Pedro Batista
This paper presents a novel nonlinear backstepping control law for continuous, low-thrust station-keeping in the Earth-Moon system. Quasi-periodic libration point orbits are target…
