velocity profile. The Simulink model is a much simplified version of a velocity control loop

which adjusts the fuel flow rate to control the aircraft velocity. The model includes

elements to model fuel consumption and resulting changes in aircraft mass as well as

nonlinear draft effects limiting aircraft velocity. Constants used in the model, such as the

drag coefficient, are defined in the model workspace and initialized from a script.

Verifying Loop Gain and Phase Margins

The aircraft model contains a Check Gain and Phase Margins block from the

Simulink Control Design Model Verification library. This block computes the linearization

of the loop seen by the Velocity Controller block every 30 minutes of simulated

time.
