models: implement simple fixedwing model #209

Closed sjschlapbach closed 1 year ago

sjschlapbach commented 1 year ago

This pull request introduces a modified model for a fixedwing standard plane with linear lift model (function of angle of attack and elevator input) and quadratic drag model.

An additional "--normalization" flag was introduced to have the ability to disable normalization when using simulation data or the new flight log standards with setpoints. The model can be run with the same makefile command as mentioned in the README:

make estimate-model model=fixedwing_longitudinal_model log=resources/elevator_ramp_zero_thrust.csv

For VTOL configurations (with different PX4 setpoint topics for the correct control surfaces and thrust quantities), use the following configuration:

make estimate-model model=vtol_longitudinal_model log=LOG_PATH

@sjschlapbach I think I am getting a different issue as you have showed in the meeting.

Is this consistent of what you are expecting in this branch?

Plotting currently doesn't work for this model, but the estimation can still be run with the following command:

python3 Tools/parametric_model/generate_parametric_model.py --plot False --config Tools/parametric_model/configs/fixedwing_longitudinal_model.yaml resources/elevator_ramp_zero_thrust.csv

Before I review the PR, would it be possible to address the CI failures? e.g.

@sjschlapbach Could we try to separate the changes we want to merge?

Some things need to happen for this to get merged

sjschlapbach commented 1 year ago

@sjschlapbach How was the quadrotor_model data generated? They seem to have been modifield

@Jaeyoung-Lim The new flight time computation (in dataframe_tools) is based on the vehicle_status/landed topic, which was missing from the csv files (as it was not used before). To ensure that the estimation still works with these logs, I added the landed column and filled it with zeros.

@sjschlapbach Thanks!

Bombs away!
