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

Get the latest artefacts from the blackbox-log-viewer https://github.com/pichim/blackbox-log-viewer/actions/runs/8053874808 and install it.
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:
