frestimate
Frequency response estimation of Simulink models
Syntax
sysest = frestimate(model,io,input)
sysest = frestimate(model,op,io,input)
[sysest,simout] = frestimate(model,op,io,input)
[ ] = = frestimate( ,options)
sysest = frestimate(data,freqs,units)
Description
sysest = frestimate(model,io,input) estimates the frequency response of a
Simulink model using the specified input signal, the operating point defined by the model
initial conditions, and the analysis points specified in io.
sysest = frestimate(model,op,io,input) initializes the model at the operating
point op before estimating the frequency response. If the model initial conditions are not
at steady state or not the operating point of interest, use this syntax to specify a different
operating point.
[sysest,simout] = frestimate(model,op,io,input) also returns the simulated
model output. Use this syntax when you want to examine the estimation results using the
Simulation Results Viewer (frest.simView).
[ ] = = frestimate( ,options) computes the frequency response using
additional options. You can use this syntax with any of the previous input and output
argument combinations.
sysest = frestimate(data,freqs,units) estimates the frequency response using
simulation data obtained using the Frequency Response Estimator block in offline
estimation mode. Use this syntax only with data logged using that block.
