Visualize Linear System at Multiple Simulation
Snapshots
This example shows how to visualize linear system characteristics of a nonlinear Simulink
model at multiple simulation snapshots.(^1) Open Simulink model.
For example:
watertank
(^2) Open the Simulink Library Browser by selecting View > Library Browser in the
model window.
(^3) Add a plot block to the Simulink model.
a In the Simulink Control Design library, select Linear Analysis Plots.
b Drag and drop a block, such as the Gain and Phase Margin Plot block, into the
Simulink model window.
The model now resembles the following figure.
(^4) Double-click the block to open the Block Parameters dialog box.
To learn more about the block parameters, see the block reference pages.
(^5) Specify the linearization I/O points.
The linear system is computed for the Water-Tank System.
