Fabian,

To understand what I did, it is best to look at the FullForm of a TransferFunctionModel:

It has the Form of TransferFunctionModel[{...},s, SystemsModelLabels->{{inputs..., outputs...}}]

So I used pattern matching to extract the argument to SystemModelLabels-> xxx_. I had to use Rule[] because I am pattern matching the argument to a rule.

Regards,

Neil

Fabian,

I do not know of a way to do this with the built in commands, However, you can easily write your own.

You can get the labels with this command:

labels = Cases[model , Rule[SystemsModelLabels, lst_] -> lst][[1]]

From this you can create your own mySystemsModelExtract that finds the labels in the list of labels above (by Position) and feeds that to the SystemsModelExtract function. You need to decide on a syntax for your command but it should work well.

Regards,

Neil
