Fault-tolerant flight control for the Cessna Citation 500. First use of Deep Reinforcement Learning for a jet aircraft flight controller. The code was developed for a Master's thesis entitled Deep Reinforcement Learning for Flight Control.

MacOS users can use the module straight away. Linux and Windows users are required to recompile the CitAST high-fidelity simulation model as instructed in docs/CitAST_for_Python.pdf.

1. Clone fault-tolerant-flight-control-drl

cd <installation_path_of_your_choice>
git clone https://github.com/kdally/fault-tolerant-flight-control-drl
cd fault-tolerant-flight-control-drl

2. Create a new conda environment with the required packages

conda env create -f environment.yml
conda activate ftc-drl
python setup.py install

1. To fly the aircraft right away with pre-trained agents 🛩

python tests/test_all.py

Select flight settings on the GUI. Default choices are recommended for unexperienced users.

2. To retrain the inner-loop and outer-loop controllers ⚙️

python tests/train_inner_loop.py
python tests/train_outer_loop.py

3. To perform a hyperparameter optimization 🎯

python tests/optimization.py
