Nested feedback loops — Block Diagram

A multi-loop control block diagram — an inner loop closes G2·G3 around sensor H1, an outer loop closes the whole forward path around sensor H2 routed over the top, and two summing junctions combine the reference with each feedback signal. The kind of cascaded architecture a generic flowchart can't lay out.

シナリオ

Cascaded and nested control loops are everywhere in real plants — an inner velocity loop inside an outer position loop, an inner current loop inside a speed loop. Textbooks (Ogata, Franklin) draw them as block diagrams with multiple summing junctions and feedback paths that cross over the forward chain. Schematex routes those crossings automatically from a signal-flow description.
