Setting Up Models

A model in the Model-Based Calibration Toolbox is a function of a set of variables. Typically, you construct a model using the Model Browser; then you can use CAGE to calibrate lookup tables by reference to the model.

The following example uses a model of how torque behaves with varying spark angle, air-fuel ratio, engine speed, and load.

Importing a Model

To import a model built using the Model Browser:

1. Select File -> Import -> Model, which starts the Model Import Wizard.

   

2. Click  to browse for the correct model file.
3. Select the tutorial.exm file, found in matlab\toolbox\mbc\mbctraining (this is a copy of the torque model built in the Model Browser's quick start tutorial) and click Open.
4. To accept the default setting, leave Open as: Automatic and click Next.
5. There are two models stored in this file, tq and knot. Highlight tq and click Next to show the following.

   

1. CAGE automatically assigns variables in the variable dictionary to the model input factors or their aliases (as long as names are exact).

6. Click Finish to complete the wizard.

When you complete the wizard, you return to the Models view.

For more information about models, see Setting Up Your Models.
