Remove all points from list of analysis points in slLinearizer or slTuner interface





removeAllPoints(s) removes all points from the list of analysis points for the slLinearizer or slTuner interface, s. This function 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 all signals from the list of interface analysis points.


To verify that all analysis points have been removed, display the contents of sllin, and examine the information about the interface analysis points.

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.
