Batch Compute Steady-State Operating Points Reusing

Generated MATLAB Code

This example shows how to batch-compute steady-state operating points for a model

using generated MATLAB code. You can either simulate or linearize your model at these

operating points and study the change in model behavior.

If you are new to writing scripts, interactively configure your operating points search

using the Steady State Manager or Linear Analysis Tool.

Before generating code for batch trimming, first compute an operating point to meet an

instance of your specifications. For more information on computing operating points in:

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


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

After computing an operating point, generate a MATLAB script. To do so in the:

• In Steady State Manager, on the Specification tab, click Trim , and select
  Script.


• In Linear Analysis, in the Trim the model dialog box, click Generate MATLAB
  Script.

For more information on generating scripts, see “Generate MATLAB Code for Operating

Point Configuration” on page 1-145.

The generated script opens in the MATLAB Editor window. You can then modify the script

to trim the model at multiple operating points.

This example demonstrates batch trimming using the magball Simulink model.

(^1) Open the model.
open_system('magball')
(^2) To open the Steady State Manager, in the Simulink model window, select Analysis

Control Design > Steady State Manager.
(^3) On the Steady State tab, click Trim Specification.
