System Dynamics Modeling
Deriving the system dynamics is systematically done using free-body diagrams, one diagram per body:
The sign of spring and damper forces are easily determined by considering the motion of one state ...

Calculating the transfer function of this block diagram
Assuming scalars (i.e. SISO systems):
$$\begin{align}
C&=E_1G_3+E_2G_2\\
E_1&=R-CH\\
E_2&=E_1G_1-CG_4=(R-CH)G_1-CG_4\\
\end{align}$$
Hence
$$\begin{align}C&=(R-CH)G_3+((R-CH)G_1-CG_4)...

How to get difference equation from this block diagram
You can label each node and form a matrix equation:
You get equations:
$$\begin{align}x_0&=x[n]\\
x_1&=-x_0+x_3+x_4\\
x_2&=2x_1\\
x_3&=z^{-1}x_0+2x_4\\
x_4&=z^{-1}x_2+z^{-1}x_5\\
...
