Remove point from list of analysis points in slLinearizer or slTuner interface
removePoint( removes
the specified point, s,pt)pt, from the list of analysis points for
the slLinearizer or slTuner interface, s.
You can specify pt to remove either a single
or multiple points.
removePoint does not modify the model associated
with s.
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 the y1m point from the interface.
removePoint(sllin,'y1m');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 the y1m and e1 points from the interface.
removePoint(sllin,{'y1m','e1'});Create an slLinearizer interface for the scdcascade model. Add analysis points for the r, e1, and y1m signals.
sllin = slLinearizer('scdcascade',{'r','e1','y1m'});
Determine the index number of the point you want to remove. To do this, display the contents of the interface, which includes analysis point index numbers, in the Command Window.
For this example, remove the y1m point from sllin.

s — Interface to Simulink® modelslLinearizer interface | slTuner interfaceInterface to a Simulink model, specified as either an slLinearizer interface or an slTuner interface.
pt — Analysis pointAnalysis point to
remove from the list of analysis points for s,
specified as:
Character vector or string — Analysis point signal name.
To determine the signal name associated with an analysis point,
type s. The software displays the contents of s in
the MATLAB® command window, including the analysis point signal
names, block names, and port numbers. Suppose an analysis point does
not have a signal name, but only a block name and port number. You
can specify pt as the block name.
You can specify pt as a uniquely matching
portion of the full signal name or block name. Suppose the full signal
name of an analysis point is 'LoadTorque'. You
can specify pt as 'Torque' as
long as 'Torque' is not a portion of the signal
name for any other analysis point of s.
For example, pt = 'y1m'.
Cell array of character vectors or string array —
Specifies multiple analysis point names. For example, pt
= {'y1m','y2m'}.
Positive integer or — Analysis point index.
To determine the index of an analysis point, type s.
The software displays the contents of s in the MATLAB command
window, including the analysis points indices.
For example, pt = 1.
Vector of positive integers — Specifies multiple
analysis point indices. For example, pt = [1 2].
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.
