A GUI to Set Simulink
®
Model Parameters (GUIDE)
F14 Controller Gain Editor
You can use the F14 Controller Gain Editor to analyze how changing the
gains used in the Proportional-Integral Controller affect the aircraft’s angle of
attack and the amount of G force the pilot feels.
Note that the Simulink diagram
f14.mdl must be open to run this GUI. If
you close the F14 Simulink model, the G UI r eopens it whenever it requires
the model to execute.
Change the Controller Gains
You can change gains in two blocks:
1 The P roportional gain (Kf)intheGainblock
2 The Integral gain (Ki) in the Transfer Function block
You can change either of the gains in one of the two ways:
1 Move the slider associated with that gain.
2 Type a new value into the Current value edit field associated with that
gain.
The block’s values are updated as soon as you enter the new value in the GUI.
Run the Simulation
Once you have set the gain values, you can run the simulation by clicking
the Simulate and store results button. The simulation time and output
vectors are stored in the Results list.
Plot the Results
You can generate a plot of one or more simulation results by selecting the
row of results (
Run1, Run2, etc.) in the Results list that you want to plot
and clicking the Plot button. If you select multiple rows, the graph contains
aplotofeachresult.
