Feedback: a zooming principle

Back
Abstract:
Feedback is the core concept of control theory, a branch of engineering that developed during the second half of the 20th century in the shade of computer science, circuit theory, and artificial intelligence. As a concept that is central to life and pervasive in modern technology, the status of feedback as a scientific concept is ambiguous, somewhere between "the crystal and the smoke". For most politely educated engineers, feedback is good souvenir, an interesting historical development of the pre-digital age. The talk will revisit some key developments of feedback science, some of its magics, some of its mysteries, and some of its promises. We will argue that feedback is a zooming principle, thereby central to multi-resolution modeling, analysis, and design. And that the age of big data, network science, and brain initiatives is a renaissance period for the most philosophical concept of engineering.
