B-spline shaping for low-thrust interplanetary rendezvous
Julio C. Sanchez
Rapid preliminary design of low-thrust interplanetary rendezvous trajectories requires parameterizations that combine computational efficiency, flexibility, and sufficient solution…
Orbit-Attitude Predictive Control in the Vicinity of Asteroids with In Situ Gravity Estimation
Julio C. Sanchez, Rafael Vazquez, James D. Biggs +1
This paper presents an integrated model-learning predictive control scheme for spacecraft orbit-attitude station-keeping in the vicinity of asteroids. The orbiting probe relies on…
Event-Based Impulsive Control for Spacecraft Rendezvous Hovering Phases
Julio C. Sanchez, Christophe Louembet, Francisco Gavilan +1
This work presents an event-triggered controller for spacecraft rendezvous hovering phases. The goal is to maintain the chaser within a bounded region with respect to the target. T…
Chance-constrained Model Predictive Control for Near Rectilinear Halo Orbit spacecraft rendezvous
Julio C. Sanchez, Francisco Gavilan, Rafael Vazquez
This work presents a robust Model Predictive Controller (MPC) to solve the problem of spacecraft rendezvous in the context of the restricted three-body problem (R3BP) as will be re…
A flatness-based predictive controller for six-degrees of freedom spacecraft rendezvous
Julio C. Sanchez, Francisco Gavilan, Rafael Vazquez +1
This work presents a closed-loop guidance algorithm for six-degrees of freedom spacecraft rendezvous with a passive target flying in an eccentric orbit. The main assumption is that…
