Simulink Control Design™ - MathWorks

In the Initialize Model dialog box, select MATLAB Workspace, and click OK. The

software exports the operating point to the MATLAB® workspace and initializes the

model with the inputs and states in the operating point.

Collect Frequency Response Data

To collect frequency response data, you must first specify an input signal. For this

example, use a fixed-step sinestream signal. For more information on defining sinestream

input signals, see “Sinestream Input Signals” on page 5-37.

On the Estimation tab, in the Input Signal drop-down list, click Fixed Sample Time

Sinestream.
