Diffusion-Based Multiple-Shooting Indirect Optimal Control for Fuel-Optimal Spacecraft Trajectory Generation
Saeid Tafazzol, Ehsan Taheri, Ryne Beeson
Diffusion-based generative models (DMs) have found applications in control problems, and in particular robotics, where the DMs enable exploration of possible control solutions. A c…
Comparison of control regularization techniques for minimum-fuel low-thrust trajectory design using indirect methods
Saeid Tafazzol, Ehsan Taheri, Nan Li
Minimum-fuel low-thrust trajectories typically consist of a finite, yet unknown number of switches in the thrust magnitude profile. This optimality-driven characteristic of minimum…
Expanding the Class of Quadratic Control-Lyapunov Functions for Low-Thrust Trajectory Optimization
Nicholas P. Nurre, Saeid Tafazzol, Ehsan Taheri
Control laws derived from Control-Lyapunov Functions (CLFs) offer an efficient way for generating near-optimal many-revolution low-thrust trajectories. A common approach to constru…
Rapid Determination of Low-Thrust Spacecraft Reachable Sets in Two-Body and Cislunar Problems
Sean R. Bowerfind, Ehsan Taheri
The reachable set of controlled dynamical systems consist of the set of all possible reachable states from an initial condition, over a certain period of time under various control…
Minimum-Time Trajectory Optimization With Data-Based Models: A Linear Programming Approach
Nan Li, Ehsan Taheri, Ilya Kolmanovsky +1
In this paper, we develop a computationally-efficient approach to minimum-time trajectory optimization using input-output data-based models, to produce an end-to-end data-to-contro…
