8-hour velocity profile. The model is a simplified version of a velocity control loop,
which adjusts the fuel flow rate to control the aircraft velocity.The model includes blocks to model:- Fuel consumption and resulting changes in aircraft mass
- 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.The v <= 0.9*vCruise and Assert that: PM >= 60 or if PM < 60 then v
<= 0.9*vCruise blocks are Check Static Upper Bound and Assertion blocks,
respectively, from the Simulink Model Verification library. In this example, you use
these blocks with the Check Gain and Phase Margins block to design a complex logic
for assertion.(^2) View the linearization input, output and settings in the Linearizations tab of the
Check Gain and Phase Margins block parameters dialog box.
