Feedback Circuit schematic to Control Theory block diagram?

I'm studying analog electronics circuit with feedback.

I see that, during analysis, a useful abstraction over the schematic is the block diagram in control theory style, but I stuggle in deriving it from the schematic.

Also, I found a lot of textbooks describing the problem either from electronics point of view or from control theory's one.

Does anyone have a good recommendation for material which attempts to fill the gap and derive the block diagram starting from the circuit?
