LQR Design For Formation Flying Near Halo Orbits Exploiting Quasi-Periodic Symmetry In Toroidal Coordinates
Joaquin G. Lopez-Cepero, Rafael Vazquez, Julio C. Sanchez
This work presents the design of a Linear Quadratic Regulator for relative motion control near periodic orbits in the Circular Restricted Three-Body Problem (CR3BP), formulated in…
A Switching Strategy for Event-Trigger Control of Spacecraft Rendezvous
Tommaso Del Carro, Gerson Portilla, Alexandre Seuret +1
This paper presents the design of a state-feedback control law for spacecraft rendezvous, formulated using the Hill-Clohessy-Wiltshire equations. The proposed method introduces an…
Backstepping Control Laws for Higher-Dimensional PDEs: Spatial Invariance and Domain Extension Methods
Rafael Vazquez
This paper extends backstepping to higher-dimensional PDEs by leveraging domain symmetries and structural properties. We systematically address three increasingly complex scenarios…
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…
A hybrid dynamical system approach to the impulsive control of spacecraft rendezvous (extended version)
Alexandre Seuret, Rafael Vazquez, Luca Zaccarian
This paper introduces a hybrid dynamical system methodology for managing impulsive control in spacecraft rendezvous and proximity operations under the Hill-Clohessy-Wiltshire model…
