Polynomial-Based Solutions to Targeting Problems for Onboard Applications
Adam Evans, Alberto Fossa, Roberto Armellin +2
This paper solves the targeting problem focusing on accuracy, computational efficiency, and reliability. The trajectory optimization problem is first recast as a polynomial optimiz…
Exoplanetary Tour Design with Solar Sails: TheAntipodes Results in the GTOC13 Problem
Jack Yarndley, Adam Evans, Xingyu Zhou +2
Solar sails present an attractive but challenging propulsion method for large-scale, long-duration trajectory design problems. In 2025, the 13th Global Trajectory Optimization Comp…
Sample-Free Safety Assessment of Neural Network Controllers via Taylor Methods
Adam Evans, Roberto Armellin
In recent years, artificial neural networks have been increasingly studied as feedback controllers for guidance problems. While effective in complex scenarios, they lack the verifi…
Learning-Based Stable Optimal Guidance for Spacecraft Close-Proximity Operations
Kun Wang, Roberto Armellin, Adam Evans +2
Machine learning techniques have demonstrated their effectiveness in achieving autonomy and optimality for nonlinear and high-dimensional dynamical systems. However, traditional bl…
