Post Capture Detumble Trajectory Optimization

This repository contains the code for Post-capture detumble trajectory stabilization for robotic active debris removal

The PostCapDetumbleTrajectory class is provided in the file PostCapDetumbleTrajOpt.py. The TVLQRTrajectoryStabilizer class is provided in the file TrajectoryStabilizationTVLQR.py. Example use of these classes can be seen in the application folder asr_paper_system.

Depencencies

The repository has the following dependencies:

• numpy
• Drake (https://drake.mit.edu/) (Install via apt or tarball as SNOPT is not installed via pip and this solver is used for trajectory optimization)
• toml
• matplotlib
• pickle

Folder Organization

• asr_paper_system: Contains the code for the system used in the following paper: Vyas, S., Maywald, L., Kumar, S., Jankovic, M., Mueller, A. and Kirchner, F., 2022. Post-capture detumble trajectory stabilization for robotic active debris removal. Advances in Space Research.
