Simulink Control Design™ - MathWorks

sllin = slLinearizer(mdl,pt,op,param,blocksub,options) uses any

combination of the input arguments pt, op, param, blocksub, and options to create

sllin.

For example, use any of the following:

• sllin = slLinearizer(mdl,pt,param)


• sllin = slLinearizer(mdl,op,param).

If you do not specify pt, the interface adds the linear analysis points marked in the model

as analysis points. The interface also adds linear analysis points that imply an opening as

permanent openings.

Object Description

slLinearizer provides an interface between a Simulink model and the linearization

commands getIOTransfer, getLoopTransfer, getSensitivity, and

getCompSensitivity. Use slLinearizer to efficiently batch linearize a model. You

can configure the slLinearizer interface to linearize a model at a range of operating

points and specify variations for model parameter values. Use interface analysis points on

page 15-271 and permanent openings on page 15-272 to obtain linearizations for any

open-loop or closed-loop transfer function from a model. Analyze the stability, or time-

domain or frequency-domain characteristics of the linearized models.

If you changed any interface properties since the last linearization, commands that

extract linearizations from the slLinearizer interface recompile the Simulink model. If

you made calls to specific functions since the last linearization, the commands also

recompile the Simulink model. These functions include addPoint, addOpening,

removePoint, removeOpening, removeAllPoints, and removeAllOpenings.

Examples

Create and Configure slLinearizer Interface for Batch Linear Analysis

Create an slLinearizer interface for the scdcascade model. Add analysis points to

the interface to extract open- or closed-loop transfer functions from the model. Configure

the interface to vary parameters and operating points.
