Higher-Order Gravitational Models: A Tutorial on Spherical Harmonics and the Newtonian Model
Felipe Arenas-Uribe
Accurate modeling of gravitational interactions is fundamental to the analysis, prediction, and control of space systems. While the Newtonian point-mass approximation suffices for…

Geometric Conditions for Lossless Convexification in Linear Optimal Control with Discrete-Valued Inputs: Real-Time Implementation for Spacecraft Rendezvous
Felipe Arenas-Uribe, Hasan A. Poonawala, Jesse B. Hoagg
Optimal control problems with discrete-valued inputs are inherently challenging due to their mixed-integer nature, rendering them generally intractable for real-time, safety-critic…

Safe Landing on Small Celestial Bodies with Gravitational Uncertainty Using Disturbance Estimation and Control Barrier Functions
Felipe Arenas-Uribe, T. Michael Seigler, Jesse B. Hoagg
Soft landing on small celestial bodies (SCBs) poses unique challenges, as gravitational models poorly characterize the higher-order gravitational effects of SCBs. Existing control…
