The concept of feedback
· Compare the following two interconnections:
or forcing. The term feedback refers to a situation in which
al systems are connected together such that each system
d their dynamics are thus strongly coupled. Simple causal
back system is difficult because the first system influences
nd system influences the first, leading to a circular argument.
