The model also includes a Nichols Plot block from the Simulink Control Design Linear
Analysis Plots library, which computes the loop response as the fuel mass drops during
the simulation. The Generate dynamic range events block generates a rising edge
whenever the fuel mass is a multiple of 10% of the maximum fuel mass. These rising
edges trigger a linearization and display the results on the Nichols plot. The Show Plot in
the Block Parameters dialog box opens the Nichols plot.The Signal Builder block in the model defines the velocity profile for the aircraft.
Double click the block to show the Verification Manager Tool which displays the check
blocks included in the model. See “Construct Simulation Tests by Using the Verification
Manager” (Simulink) for more information.14 Model Verification
