Under-Approximating Reach-Avoid Sets for Space Vehicle Maneuvering in the Presence of Debris

Autor: R. Scott Erwin, Meeko M. K. Oishi, Matt Shubert, Morgan Baldwin

Publikováno v: IFAC-PapersOnLine. 51:142-147

We investigate the safety verification of a satellite attempting to maneuver to a new position while avoiding multiple debris. We assume that the satellite, desired rendezvous point, and debris are near the same circular orbit, with dynamics modeled

The problem of distributed networked sensor agents jointly estimating the state of a plant given by a linear time-invariant system is studied. Each agent can only measure the output of the plant at intermittent time instances, at which times the agen

Multiple-Object Space Surveillance Tracking Using Finite-Set Statistics

Autor: Moriba Jah, Carolin Frueh, Islam I. Hussein, Kyle J. DeMars, R. Scott Erwin

Publikováno v: Journal of Guidance, Control, and Dynamics. 38:1741-1756

The dynamic tracking of objects is, in general, concerned with state estimation using imperfect data. Multiple object tracking adds the difficulty of encountering unknown associations between the collected data and the objects. State estimation of ob

Safe Positively Invariant Sets for Spacecraft Obstacle Avoidance

Autor: R. Scott Erwin, Christopher D. Petersen, Ilya Kolmanovsky, Avishai Weiss, Morgan Baldwin

Publikováno v: Journal of Guidance, Control, and Dynamics. 38:720-732

This paper presents an obstacle avoidance method for spacecraft relative motion control. In this approach, a connectivity graph is constructed for a set of relative frame points, which form a virtu...

Model Predictive Control with Ellipsoid Obstacle Constraints for Spacecraft Rendezvous

Autor: Christopher Jewison, R. Scott Erwin, Alvar Saenz-Otero

Publikováno v: IFAC-PapersOnLine. 48:257-262

The problem of spacecraft rendezvous with obstacle avoidance constraints is explored. A Model Predictive Control (MPC) approach is used to compute an optimal control strategy for a chaser attempting to rendezvous with a target spacecraft in Earth orb

On the tractability of satellite range scheduling

Autor: Antonio J. Vazquez, R. Scott Erwin

Publikováno v: Optimization Letters. 9:311-327

Scheduling of contacts between several satellites and ground stations has been historically sub-optimally approached. This fact raises the question: can this problem be solved in polynomial time? Although existing literature provided optimal solution

On-Orbit Operational Range Computation Using Gauss’s Variational Equations with J2 Perturbations

Autor: Daniel J. Scheeres, Marcus J. Holzinger, R. Scott Erwin

Publikováno v: Journal of Guidance, Control, and Dynamics. 37:608-622

Aircraft operational range, the distance an aircraft can travel with a fixed quantity of fuel, is an intuitive measure that provides strategic and tactical insight to the end user. Currently, there is no rigorously defined and derived operational ran

Viable set approximation for linear-Gaussian systems with unknown, bounded variance

Autor: Joseph D. Gleason, R. Scott Erwin, Abraham P. Vinod, Meeko M. K. Oishi

Publikováno v: CDC

Computation of stochastic reachable and viable sets enables assurances of safety and feasibility through the synthesis of optimal control policies. These control policies are typically generated under the assumption of accurate characterization of ad

Computing reach-avoid sets for space vehicle docking under continuous thrust

Autor: Morgan Baldwin, Matt Shubert, R. Scott Erwin, Meeko M. K. Oishi, Baisravan HomChaudhuri

Publikováno v: CDC

We compute the reach-avoid set for space vehicle rendezvous and docking under continuous thrust. We model the space vehicle dynamics through the Clohessy-Wiltshire-Hill (CWH) equations, resulting in a switched hybrid system with affine, time-invarian
