Description
The code above is a LaTeX document that creates a block diagram using the blox and tikz packages. The diagram consists of several blocks and links that represent a control system with feedback. The blocks represent various transfer functions (Gc, G1, G2, G3, H1, and H2), while the links represent signals or variables (R(s), D(s), C(s), and the output). The code also includes various tikz styles and libraries for drawing the diagram elements, such as the connect style for drawing curved links over a block, and the tkz-euclide library for drawing geometric elements such as angles and circles.
