Simulink Control Design™ - MathWorks

(^2) Simulate the model to obtain the output signal. For example:
[sysest,simout] = frestimate(model,op,io,in_ts)
The second output argument of frestimate, simout, is a Simulink.Timeseries
object that stores the simulated output. in_ts is the corresponding input data.
(^3) Generate timeseries objects before using with other MathWorks® products:
input = generateTimeseries(in_ts);
output = simout{1}.Data;
You can use data from timeseries objects directly in Signal Processing Toolbox
software, or convert these objects to System Identification Toolbox data format. For
examples, see “Estimate Frequency Response Models with Noise Using Signal
Processing Toolbox” on page 5-75 and “Estimate Frequency Response Models with
Noise Using System Identification Toolbox” on page 5-77.
For a related example, see “Disable Noise Sources During Frequency Response
Estimation” on page 5-69.
