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…
Designing trajectories in the Earth--Moon system: a Levenberg--Marquardt approach
António Nunes, Sérgio Brás, Pedro Batista +1
Trajectory design in cislunar space under a high-fidelity ephemeris model (HFEM) is pursued through a nonlinear optimization perspective anchored on the transition of solutions fro…
