Compute Operating Points from Specifications Using


Linear Analysis Tool


You can compute a steady-state operating point of a Simulink model by specifying
constraints on the model states, outputs, and inputs, and finding a model operating
condition that satisfies these constraints. For more information on steady-state operating
points, see “About Operating Points” on page 1-3 and “Compute Steady-State Operating
Points” on page 1-6.

To find an operating point for your Simulink model, you can interactively trim your model
using the Linear Analysis Tool, as shown in this example.

Alternatively, you can trim your model:


  • In the Steady State Manager. For more information, see “Compute Operating Points
    from Specifications Using Steady State Manager” on page 1-23.

  • At the command line. For more information, see “Compute Operating Points from
    Specifications at the Command Line” on page 1-17.


In this example, you compute an operating point to meet state specifications. Using a
similar approach, you can define output or input specifications. Also, you can define a
combination of state, output, and input specifications; that is, you do not have to use, for
example, only state specifications.

For more information on trimming your model to meet specifications, see “Compute
Steady-State Operating Points from Specifications” on page 1-15.
