Quick Start for Performing Linear Analysis Using the LTI Viewer

In this Quick Start, 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 Building Models.

To perform linear analysis:

1. Open the LTI Viewer showing one or more models using the following syntax:

   ltiview(model1,model2,...,modelN)

   By default, this syntax opens a step response plot of your models, as shown in the following figure.

   

2. Add more plots to the LTI Viewer.

   1. Select Edit > Plot Configurations.

   2. In the Plot Configurations dialog box, select the number of plots to open.

   

3. To view a different type of response on a plot, right-click and select a plot type.

   

4. Analyze system performance. For example, you can analyze the peak response in the Bode plot and settling time in the step response plot.

   1. Right-click to select performance characteristics.

   2. Click on the dot that appears to view the characteristic value.
