Creating Graphical User Interfaces    

How to Use the GUI (Text of GUI Help)

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 GUI reopens it whenever it requires the model to execute.

Changing the Controller Gains

You can change gains in two blocks:

You can change either of the gains in one of the two ways:

The block's values are updated as soon as you enter the new value in the GUI.

Running 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.

Plotting 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 a plot of each result.

The graph is displayed in a figure, which is cleared each time you click the Plot button. The figure's handle is hidden so that only the GUI can display graphs in this window.

Removing Results

To remove a result from the Results list, select the row or rows you want to remove and click the Remove button.
