In this example, if you place a loop opening at the same location as the linearization
output point, the effect of the inner loop is also removed from the linearization result.

Ways to Specify Portion of Model to Linearize

There are several ways to define the portion of the model you want to linearize using
linear analysis points. Each method has its own advantages and depends on which
linearization tool you use. For more information on choosing linearization tools, see
“Choose Linearization Tools” on page 2-9.

You want to save the analysis points

directly in the model or graphically

display the analysis points within

the model.

Using Linear

Analysis Tool

You want to linearize your model

interactively using the Linear

Analysis Tool without changing the

Simulink model. Using this method

you can specify multiple open-loop

or closed-loop transfer functions for

your model.

At command line

using linio

command

You want to linearize your model

using the linearize command.

Using linio does not change the

Simulink model.

Linearize at Command Line” on

Using

slLinearizer

interface

You want to obtain multiple open-

loop or closed-loop transfer

functions from the linearized

system without recompiling the

model. Using this method does not

change the Simulink model.
