To create a transient analysis plot in the System Identification app, select the Transient resp check box in the Model Views area. For general information about creating and working with plots, see Working with Plots.
To include or exclude a model on the plot, click the corresponding model icon in the System Identification app. Active models display a thick line inside the Model Board icon.
The following table summarizes the Transient Response plot settings.
Transient Response Plot Settings
|Display step response for linear or nonlinear model.|
Select Options > Step response.
|Display impulse response for linear model.|
Select Options > Impulse response.
Display the confidence interval.
Change time span over which the impulse or step response is calculated. For a scalar time span T, the resulting response is plotted from -T/4 to T.
|Toggle between line plot or stem plot.|
Select Style > Line plot or Style > Stem plot.
(Multiple-output system only)
Select the output by name in the Channel menu.
If the plotted models include a noise
model, you can display the transient response properties associated
with each output channel. The name of the channel has the format
(Step response for nonlinear models only)
Select Options > Step Size, and then chose from two options:
