Data Supported by Grey-Box Models
You can estimate both continuous-time or discrete-time grey-box
models for data with the following characteristics:
Time-domain or frequency-domain data, including time-series
data with no inputs.
Note
Nonlinear grey-box models support only time-domain data. |
Single-output or multiple-output data
You must first import your data into the MATLAB workspace.
If you are using the System Identification Tool GUI, then import the
data into the GUI to make the data available to the toolbox. However,
if you prefer to work at the command line, then represent your data
as an iddata or idfrd object. For more information about
preparing data for identification, see Data Import and Processing.
