Description

Linearization Manager lets you configure linear analysis points in your Simulink® model and configure custom block linearizations. When you open the app, the Linearization tab is added to the toolstrip.

Using this app, you can:

  • Insert linear open-loop and closed-loop linear analysis points.

  • Insert trim output constraints.

  • Specify custom block linearizations using MATLAB® expressions or configuration functions.

  • Open the Steady State Manager app for model trimming.

  • Open the Model Linearizer app for model linearization and frequency response estimation.

Linearization Manager app

Open the Linearization Manager App

On the Apps tab, under Control Systems, click Linearization Manager. The Linearization tab opens.

To specify a linear analysis point in your Simulink model:

In the model, click the signal you want to define as an analysis point.

On the Linearization tab, in the Insert Analysis Points gallery, select the type of analysis point you want to define.

  • Input Perturbation — Specifies an additive input to a signal.

  • Output Measurement — Takes a measurement at a signal.

  • Loop Break — Specifies a loop opening.

  • Open-Loop Input — Specifies a loop break followed by an input perturbation.

  • Open-Loop Output — Specifies an output measurement followed by a loop break.

  • Loop Transfer — Specifies an output measurement before a loop break followed by an input perturbation.

  • Sensitivity — Specifies an input perturbation followed by an output measurement.

  • Complementary Sensitivity — Specifies an output measurement followed by an input perturbation.

For more information on the different types of analysis points, see Specify Portion of Model to Linearize.

When you specify analysis points, the software adds annotations to your model indicating the linear analysis point type.

When trimming your Simulink model, you can specify additional output constraints on specific signals.

In the model, click the signal for which you want to define an output constraint.

On the Linearization tab, in the Insert Analysis Points gallery, click Trim Output Constraint.

You can now configure trimming specifications for this output constraint. For more information on trimming from specifications, see Compute Steady-State Operating Points from Specifications.
