Feedback: The Difference Between Obeying and Correcting

A3.4.1 introduced the feedback loop as a stage. This lesson asks the question that actually matters: does a system have one or not?
They monitor an environment and respond to stimuli, making them integral to automation and control.

Open-Loop and Closed-Loop Systems

Open-Loop Systems

Definition

Open-Loop System

An open-loop system operates without feedback, meaning it does not adjust based on the output.

No Feedback: The system does not monitor or adjust its output.
Predefined Actions: Operates based on preset instructions.

Example

Toasters: Heats for a set time regardless of bread color.
Washing Machines: Runs cycles based on a timer, not cleanliness.

Note

Open-loop systems are often simpler and cheaper but lack adaptability to changing conditions.
