Trimming and Linearization

Find steady-state points, extract linear model of system around operating point

Simulink® provides only basic trimming and linearization functions. For full trimming and linearization functionality, use Simulink Control Design™ software.

Functions

trimFind trim point of dynamic system
dlinmodExtract discrete-time linear state-space model around operating point
linmodExtract continuous-time linear state-space model around operating point
linmod2Extract continuous-time linear state-space model around operating point
linmodv5Extract continuous-time linear state-space model around operating point
Simulink.BlockDiagram.getInitialStateReturn initial state data of block diagram

Blocks

Timed-Based LinearizationGenerate linear models in base workspace at specific times
Trigger-Based LinearizationGenerate linear models in base workspace when triggered

Topics

Linearizing Models

Describes functions that extract a linear state-space model from a Simulink model.
