Compute Operating Points from Specifications at the

Command Line

You can compute a steady-state operating point of a Simulink® model by specifying

constraints on the model states, outputs, and inputs, and by 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 programmatically trim your

model using the findop, 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.


• Linear Analysis Tool. For more information, see “Compute Operating Points from
  Specifications Using Linear Analysis Tool” on page 1-41.

In this example, you compute an operating point to meet output specifications. Using a

similar approach, you can define state 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.
