Simulink Control Design™ - MathWorks

During the experiment, the block updates the estimated frequency response at the frd

port. The signal at this port is a vector with one value for each frequency specified by

Frequencies. You can write this signal to the MATLAB workspace using a To Workspace

block, or use Simulink data logging to write the data to the workspace as a

Simulink.SimulationData.Dataset object. The logged values show the convergence

of the frequency responses during the experiment. The most meaningful value is the value

when the experiment stops. For that reason, you can discard all values except the last

one.

For an example of a model configured to perform online frequency response estimation,

see “Online Frequency Response Estimation During Simulation” on page 6-19.
