Towards Robust Low-Thrust Trajectory Design Under Missed Thrust Events

Published in Proquest, 2026

Low-thrust spacecraft propulsion systems enable highly efficient transfers, but their low control authority and long maneuver durations make them vulnerable to maneuver execution errors, particularly missed thrust events. This dissertation develops theoretical and computational tools for robust low-thrust trajectory design under missed thrust events, with emphasis on preliminary mission design, where computational efficiency and solution robustness must be addressed simultaneously.

Initial Guess Generation for Low-Thrust Trajectory Design with Robustness to Missed-Thrust-Events

Published in Journal of Guidance, Control, and Dynamics, 2025

We propose a novel initial guess generation strategy for missed thrust design which leverages solutions from problems with lower problem complexity, demonstrating superior convergence properties relative to conventional global search methods in high-dimensional nonlinear programs.

Statistical Analysis of the Role of Invariant Manifolds on Robust Trajectories

Published in Journal of Guidance, Control, and Dynamics, 2025

Through comprehensive statistical analysis of low-thrust solutions in multibody environments, we demonstrate that optimal solutions — both robust and non-robust — exhibit strong correlation with invariant manifolds in three-body systems, establishing a fundamental connection between dynamical structures and solution robustness against operational uncertainties.
