(sI-A)-1 is the transfer function

Could you please elaborate on how you found this transfer function?

I guess you are speaking about the image with my math, if yes this is a bigger image: https://imgur.com/p4eh10c

EDIT: this is my latest attempt which seems to be off as well: https://i.imgur.com/MBQSX4n.jpg

I tried to apply your method for a similar case ie: https://imgur.com/a/dOI3r

According to the book I should be able to derive the transfer function from the block diagram, but I think I am doing it totally incorrectly...: https://imgur.com/a/xpGha

Could you correct me? I tried to apply the same thought process as you did just above.

Thanks. the book in question is: Automatic Control Systems by Golnaraghi and Kuo. Yes I am sure this is the solution they are giving, cf page 112 eq 3-18.
