@ARTICLE{2019arXiv190202726M,
author = {{Malyuta}, Danylo and {Szmuk}, Michael and {Acikmese}, Behcet},
title = "{Lossless convexification of non-convex optimal control problems with disjoint semi-continuous inputs}",
journal = {arXiv e-prints},
year = "2019",
month = "Feb",
pages = {arXiv:1902.02726}
}
```
## Installation
To run the code, you must have Python 2.7.15 and [Gurobi
8.1](http://www.gurobi.com/downloads/download-center) installed. To install
Python and other dependenies (except Gurobi) on Ubuntu, we recommend that you
install [Anaconda for Python 2.7](https://www.anaconda.com/distribution/) and
then execute (from inside this repository's directory):
```
$ conda create -n lcvx python=2.7 anaconda # Answer yes to everything
$ source activate lcvx
$ pip install -r requirements.txt
$ source activate lcvx
```
## Examples
1. Satellite docking to a rotating space station. The actuators are 12 reaction
control system (RCS) jets of which up to 4 can be fired simultaneously
2. Rocket landing with a two-mode thruster: a high-thrust low-gimbal mode and a low-thrust high-gimbal mode.
