Before you specify estimation data, create an experiment. At the MATLAB® prompt, open the nonlinear idle speed model of an automotive engine by typing
In the Parameter Estimation tool, on the Parameter Estimation tab, click New Experiment.
This action creates an experiment called
the Experiments list in the Data Browser panel
and opens the experiment editor. To change the name of the experiment,
Exp and select Rename.
If you rename it
NewData, the Experiments list
now looks like this:
To learn more about how to further modify an experiment using the experiment editor, see Experiment Editor.
After you create the experiment, you can import the estimation data into the experiment. Launch the experiment editor by right-clicking on NewData and selecting Edit....
The rows in the Inputs panel of the editor
correspond to Inport block
BPAV in the
See Import Data.
The rows in the Outputs panel correspond
to Outport block
Engine Speed. You can import signal
data from files or MATLAB workspace.
The idle-speed model of an automotive engine contains the measured
data stored in the
iodata array in the workspace.
The array contains two columns: the first for input data, and the
second for output data. The time data is in the
in the workspace. You can import the input data by typing
the dialog box in the Inputs panel.
You can import the output data by typing
the dialog box in the Outputs panel.
Note: You can have more than one input or output signal, but you can have only one data set for a signal. If you have multiple data sets, create multiple experiments.
