Exporting the Model to the MATLAB Workspace

The models you create in the System Identification Tool GUI are not automatically available in the MATLAB workspace. To make a model available to other toolboxes, the Simulink software, and the System Identification Toolbox commands, you must export your model from the System Identification Tool to the MATLAB workspace. For example, if the model is a plant that requires a controller, you can import the model from the MATLAB workspace into the Control System Toolbox product.

You must have already estimated the models, as described in Estimating Accurate Linear Models.

To export the amx3322 model, drag it to the To Workspace rectangle in the System Identification Tool GUI. The model appears in the MATLAB Workspace browser.

Note   This model is an object that belongs to the idpoly model class. To learn more about this model object, see the corresponding reference page.

After the model is in the MATLAB workspace, you can perform other operations on the model. For example, if you have the Control System Toolbox product installed, you might transform the model to a state-space LTI object using:

ss_model=ss(amx3322)

You can extract the dynamic model and ignore the noise model using the following command:

ss_model=ss_model('m')
