Reasons to Use

slLinearizer

• You are new to Simulink
  Control Design software.


• You have experience with
  the Linear Analysis Tool.


• You do not want to batch
  trim your model, which is
  not supported in the
  Linear Analysis Tool.
  
  
  • You are new to Simulink
    Control Design or have
    experience with Linear
    Analysis Tool, and you
    prefer to work at the
    command line or in a
    repeatable script.
  
  
  
  

The workflow for using

linearize closely

mirrors the workflow for

linearizing models using

the Linear Analysis Tool.

When you generate

MATLAB code from the

Linear Analysis Tool to

reproduce your session

programmatically, this

code uses linearize.

You can easily modify

this code to batch

linearize a model.

• You are extracting
  linearizations for a single
  transfer function; that is,
  only one I/O set.
  
  
  • You want to obtain
    multiple open-loop and
    closed-loop transfer
    functions without
    modifying the model or
    creating a linearization
    I/O set (using linio) for
    each transfer function.
  
  
  • You want to obtain
    multiple open-loop and
    closed-loop transfer
    functions without
    recompiling the model
    for each transfer
    function.
  
  
  
  

You can also obtain

multiple open-loop and

closed-loop transfer

functions using

linearize or the Linear

Analysis Tool. However,

the software recompiles

the model each time you

change the I/O set.
