Simulink LTI Viewer
If you have Simulink, you can use the Simulink LTI Viewer,aversionofthe
LTI Viewer that performs linear a nalysis on any portion of a Simulink mode l.
The Simulink LTI Viewer features:
Drag-and-drop blocks that identify the location for the inputs and outputs of
the portion of a Simulink model you want to analyze.
The ability to specify the operating conditions about which the Simulink
model is linearized for analysis in the LTI Viewer.
Access to all time and frequency response tools featured in the LTI Viewer.
The ability to compare a set of (linearized) models obtained by varying either
the operating conditions or some model parameter values.
Using the Simulink LTI Viewer
To learn about the Simulink LTI Viewer, we will perform some analysis on a
Simulink model for a van der Pol oscillator. To open this model, type
vdp
at the MATLAB prompt. This brings up the following diagram:
