Nucleus-Altitude-Control

Simulink model of the HAB's control logic and flight physics simulation.

1. Tweak simulation parameters and controller settings in configure_simulation.m
2. Run configure_simulation.m
3. Open ascent_simulation.slx in Simulink
4. (Optionally) Open the Data Inspector to view simulation data
5. (Optionally) Run the model and plot in 3D on a globe with run_simulation.m

Simulate a flight path using GFS data by setting use_std_atmo=false, otherwise the simulation assumes a COESA 1976 standard atmosphere. If this setting is true, running configure_simulation.m will query GFS for weather data close to the specified simulation start time and interpolate it for use a lookup table when the model runs. The data is stored in a subdir of the current working directory.

Dependencies

For standard atmosphere flight model:

• MATLAB + Simulink (Designed and tested on R2020a)

For optional flight model using GFS weather data:

• NCToolbox for reading GFS grib files. Must be placed adjacent to this repo's directory
• MATLAB Mapping Toolbox for plotting flight path on the globe

This tools was created as a design aid and exploration tool to support the control system design for Brickworks/mfc_apps.
