removeAllPoints
Remove all points from list of analysis points in slLinearizer
or slTuner
interface
Syntax
Description
removeAllPoints(
removes
all points from the list of analysis points for the s
)slLinearizer
or slTuner
interface, s
.
This function does not modify the model associated with s
.
Examples
Remove All Analysis Points
Create an slLinearizer
interface for the scdcascade
model. Add analysis points for the r
, e1
, and y1m
signals.
sllin = slLinearizer('scdcascade',{'r','e1','y1m'});
Remove all signals from the list of interface analysis points.
removeAllPoints(sllin);
To verify that all analysis points have been removed, display the contents of sllin
, and examine the information about the interface analysis points.
sllin
slLinearizer linearization interface for "scdcascade": No analysis points. Use the addPoint command to add new points. No permanent openings. Use the addOpening command to add new permanent openings. Properties with dot notation get/set access: Parameters : [] OperatingPoints : [] (model initial condition will be used.) BlockSubstitutions : [] Options : [1x1 linearize.LinearizeOptions]
Input Arguments
s
— Interface to Simulink® model
slLinearizer
interface | slTuner
interface
Interface to a Simulink model, specified as either an slLinearizer
interface or an slTuner
interface.
More About
Analysis Points
Analysis points, used
by the slLinearizer
and slTuner
interfaces,
identify locations within a model that are relevant for linear analysis
and control system tuning. You use analysis points as inputs to the
linearization commands, such as getIOTransfer
, getLoopTransfer
, getSensitivity
, and getCompSensitivity
. As inputs to the
linearization commands, analysis points can specify any open-loop
or closed-loop transfer function in a model. You can also use analysis
points to specify design requirements when tuning control systems
using commands such as systune
.
Location refers to a specific block output port within a model or to a bus element in such an output port. For convenience, you can use the name of the signal that originates from this port to refer to an analysis point.
You can add analysis points to an slLinearizer
or slTuner
interface, s
,
when you create the interface. For example:
s = slLinearizer('scdcascade',{'u1','y1'});
Alternatively, you can use the addPoint
command.
To view all the analysis points of s
, type s
at
the command prompt to display the interface contents. For each analysis
point of s
, the display includes the block name
and port number and the name of the signal that originates at this
point. You can also programmatically obtain a list of all the analysis
points using getPoints
.
For more information about how you can use analysis points, see Mark Signals of Interest for Control System Analysis and Design and Mark Signals of Interest for Batch Linearization.
