Okey, since I got no reply to my previous post above, I guess that means everything there was correct...?

Then to the following question: One of the benefits with Laplace transforms, is that you can just mulitply boxes in a row to get the transfer function for all the boxes together. In general, it's pretty simple to handle different configurations with boxes in series and in parallel, when doing transfer functions.

Is it possible as well to put up a state space representation when you have several boxes in series and so on, and how is that done then? Maybe that's a drawback to state space representations, that it's not done so easily as with transfer functions?
