Specify Portion of Model to Linearize
To linearize a subsystem, loop, or block in your model, you use analysis points. Each
analysis point that you define in the model 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.
To compute a linear model for a portion of your system, specify a linearization input point
and output point on the input and output signal to the portion of the model you want to
linearize. To compute an open-loop response, specify loop openings to break the signal
flow. You can also compute MIMO linear models by defining multiple input and output
points.Analysis Points
You can specify the following types of linear analysis points using Simulink Control Design
software. These analysis points are pure annotations and do not impact model simulation.Specify Portion of Model to Linearize
