There's a box that writes the TF of the system. I don't rembember the example i saw it in, but look it up. it may help (if i understood correctly)

The questions in this thread are really regarding System Identification. The only way to do this is using the <a href="http://sine.ni.com/nips/cds/view/p/lang/en/nid/13853" target="_blank">System Identification Toolkit</a>. LabVIEW by itself cannot do this. Once the model (transfer function, state space, etc..) has been acquired through the use of this tool, more complex design and simulation processes can be done using the <a href="http://sine.ni.com/nips/cds/view/p/lang/en/nid/203826" target="_blank">Control Design and Simulation Module</a>
