The model contains a plant in a closed-loop configuration with a PI controller. The
Frequency Response Estimator block accepts the control signal as the input u. It feeds
the control signal plus a perturbation into the plant input.The Frequency Response Estimator block is configured to run the experiment in
sinestream mode, with the same experiment parameters used in the example “Online
Frequency Response Estimation During Simulation” on page 6-19. In this example,6 Online Frequency Response Estimation
