In this example, you learn how to analyze the time- and frequency-domain responses of one or more linear models using the LTI Viewer GUI.
Before you can perform the analysis, you must have already created linear models in the MATLAB® workspace. For information on how to create a model, see Basic Models.
To perform linear analysis:
Open the LTI Viewer showing one or more models using the following syntax:
By default, this syntax opens a step response plot of your models, as shown in the following figure.
Add more plots to the LTI Viewer.
Select Edit > Plot Configurations.
In the Plot Configurations dialog box, select the number of plots to open.
To view a different type of response on a plot, right-click and select a plot type.
Analyze system performance. For example, you can analyze the peak response in the Bode plot and settling time in the step response plot.
Right-click to select performance characteristics.
Click on the dot that appears to view the characteristic value.
