Closed Loop System

A closed loop system is a control system that uses feedback to automatically adjust its output based on measured performance, maintaining stability and achieving desired outcomes. It continuously compares actual results with a set target, making corrections to minimize errors without human intervention. This concept is fundamental in engineering, automation, and various technological applications.

Also known as: Feedback Control System, Closed-Loop Control, Automatic Control System, Regulatory System, CLS

Why learn Closed Loop System?

Developers should learn about closed loop systems when working on automation, robotics, IoT devices, or any system requiring self-regulation and error correction. It's essential for building reliable control systems in industrial automation, autonomous vehicles, and smart home devices, where precise and adaptive behavior is critical.
