In the Plant Identification tab, click Get I/O data. This menu allows you to obtain
system response data in one of two ways:- Simulate Data. Obtain system response data by simulating the response of your
Simulink model to an input signal. For more information, see Design a PID Controller
Using Simulated I/O Data. - Import I/O Data. Import measured system response data as described in “Import
Measured Response Data for Plant Estimation” on page 7-67.
Once you have imported or simulated data, the Plant Identification plot displays the
response data and the response of an initial estimated plant. You can now select the plant
structure and adjust the estimated plant parameters until the response of the estimated
plant is a good fit to the response data.7 PID Controller Tuning
