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…
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…
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…
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…
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…
Statistical Analysis of the Role of Invariant Manifolds on Robust Trajectories
Amlan Sinha, Ryne Beeson
As low-thrust space missions increase in prevalence, it is becoming increasingly important to design robust trajectories against unforeseen thruster outages or missed thrust events…
Amortized Global Search for Efficient Preliminary Trajectory Design with Deep Generative Models
Anjian Li, Amlan Sinha, Ryne Beeson
Preliminary trajectory design is a global search problem that seeks multiple qualitatively different solutions to a trajectory optimization problem. Due to its high dimensionality…
