Bi-Level Optimal Control Framework For Missed-Thrust-Design With First-Order Bounds On Maximum Missed-Thrust-Duration
Amlan Sinha, Ryne Beeson
In this paper, we present a bi-level optimal control framework for designing low-thrust spacecraft trajectories with robustness against missed-thrust-events. The upper-level (UL) p…
Algorithmic Considerations for Effective Global Search of Robust Low-Thrust Trajectories
Amlan Sinha, Ryne Beeson
The growing interest in the cislunar domain over the past decade has led to an increasing demand for low-thrust missions to key orbits within this region. These low-thrust missions…
Initial Guess Generation for Low-Thrust Trajectory Design with Robustness to Missed-Thrust-Events
Amlan Sinha, Ryne Beeson
The growing interest in cislunar space exploration in recent years has driven an increasing demand for efficient low-thrust missions to key cislunar orbits. These missions, typical…
Learning Optimal Control and Dynamical Structure of Global Trajectory Search Problems with Diffusion Models
Jannik Graebner, Anjian Li, Amlan Sinha +1
Spacecraft trajectory design is a global search problem, where previous work has revealed specific solution structures that can be captured with data-driven methods. This paper exp…
Global Search of Optimal Spacecraft Trajectories using Amortization and Deep Generative Models
Ryne Beeson, Anjian Li, Amlan Sinha
Preliminary spacecraft trajectory optimization is a parameter dependent global search problem that aims to provide a set of solutions that are of high quality and diverse. In the c…
