Data Supported by Grey-Box Models
Data Supported by Grey-Box M odels
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 im port 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 Chapter
1, “Data Processing”.
