Mark Signals of Interest for Batch Linearization
When batch linearizing a model using an slLinearizer interface, you can mark signals
of interest using analysis points. You can then analyze the response of your system at any
of these points using functions such as getIOTransfer and getLoopTransfer.Alternatively, if you are batch linearizing your model using the:- Linear Analysis Tool, specify analysis points as shown in “Specify Portion of Model to
Linearize in Linear Analysis Tool” on page 2-31. - linearize command, specify analysis points using linio.
For more information on selecting a batch linearization tool, see “Choose Batch
Linearization Methods” on page 3-5.Analysis Points
Analysis points identify locations within a Simulink model that are relevant for linear
analysis. Each analysis point is associated with a signal that originates from the outport of
a Simulink block. For example, in the following model, the reference signal r and the
control signal u are analysis points that originate from the outputs of the setpoint and C
blocks respectively.Each analysis point can serve one or more of the following purposes:- Input — The software injects an additive input signal at an analysis point, for
example, to model a disturbance at the plant input. - Output — The software measures the signal value at a point, for example, to study the
impact of a disturbance on the plant output. - Loop Opening — The software interprets a break in the signal flow at a point, for
example, to study the open-loop response at the plant input.
