Supported Discrete-Time Models
Model Type
Description
Linear, input-output polynomial
models
Estimate arbitrary-order, linear parametric models from
time- or frequency-domain data.
To get a discrete-time model, your data sampling interval
must be s et to the (nonzero) value you used to sample in
your experiment.
Nonlinear black-box models
Estimate from time-domain data only.
Linear ODEs ( gre y-bo x) models Estimate ordinary difference equa t ions from tim e- or
frequency-domain data.
Nonlinear ODEs (grey-box)
models
Estimate ordinary difference equations from time-domain
data.
