bf_controller_tuning

WIP

A huge ass script to analyse bbl flight logs and tune linear filters and pids offline.

Required Matlab Toolboxes

• MATLAB
• Control System Toolbox
• Signal Processing Toolbox
• Statistics and Machine Learning Toolbox (dono why atm)

I might try to reduce the dependencies in the future.

Running the Example Script

1. Get the latest artefacts from the blackbox-log-viewer https://github.com/pichim/blackbox-log-viewer/actions/runs/8053874808 and install it.
2. Open the file 20240225_apex5_00.bbl and save it in the directory 20240225 as 20240225_apex5_00.bbl.csv.

Betaflight PR to perform the Chirp Experiments

The PR can be flashed and tested with #13105 in the betaflight-configurator.

Chirp signal generator as flight mode #13105:
betaflight/betaflight#13105

Custom Matlab Libary

To have the example running, place the libary in the same directory as bf_controller_tunning:

Custom BBLV Artefacts

Added chirp parameters to header #658:
