Aren most continuous, even mildly complex processes feedback systems?
Submitted by: stephenc Submitted on: September 27, 2004 Identifier: L1.1 Short answer: Yes. Many processes, complex or otherwise, incorporate some form of feedback. The fundamental requirement for feedback is that the system in consideration is somehow modulated, controlled, or changed by the output it produces. From an engineering perspective, usually you are looking to control a given system. This is accomplished by measuring the output, performing some kind of decision algorighm based on the output and design specs, and finally implementing an action that influences the input of the system.

When we say “open loop”, that means there is no feedback. I guess you are confused by the figure 1.1 in chapter 1. Authors really want to show you the most general form of a control system there. It can be a fee
