Linear Analysis Tool

Linearize Simulink models

Description

The Linear Analysis Tool lets you perform linear analysis of nonlinear Simulink models.

Using this tool you can:

• Interactively linearize models at different operating points


• Interactively obtain operating points by trimming or simulating models


• Perform exact linearization of nonlinear models


• Perform frequency response estimation of nonlinear models


• Batch linearize models for varying parameter values


• Generate MATLAB code for performing linearization tasks


• Generate MATLAB code for computing operating points

Open the Linear Analysis Tool App

• Simulink model editor: Select Analysis > Control Design > Linear Analysis.


• Simulink model editor: Select Analysis > Control Design > Frequency Response
  Estimation.


• Simulink model editor: Right-click a block, and select Linear Analysis > Linearize
