Simulink Control Design™ - MathWorks

Create a sinestream input signal with a 'OneAtATime' simulation order.

in = frest.Sinestream('Frequency',logspace(-1,1,50),'Amplitude',1e-3,...

'SimulationOrder','OneAtATime');

In this model, there is a single linearization input point and a single linearization output

point. There are 50 frequencies in the sinestream signal. The frestimate command

performs 50 separate Simulink simulations because the SimulationOrder parameter is

set to 'OneAtATime'.

To distribute these simulations among workers, enable parallel computing for

frestimate. Create a frequency response estimation options object using the command

frestimateOptions, and set the UseParallel parameter to 'on'. Use this object as

an input argument for frestimate.

opt = frestimateOptions('UseParallel','on');

sysest = frestimate(mdl,io,in,opt);

bode(sysest,'r*')
