Study Notes

Definition of a Control System

A control system is a set of devices or algorithms designed to manage, command, or regulate the behavior of other devices or systems.

Purpose of Control Loops

Control loops serve to maintain the desired output of a system by constantly monitoring the actual output and making adjustments as needed.

Types of Control Loops in Industries

Open-loop control: Operates without feedback, relying on predetermined commands blindly.
Closed-loop control: Utilizes feedback to compare the actual output to the desired output, allowing for real-time adjustments.
Feedback loops: Improve accuracy by instantly correcting deviations from desired performance.

Functions of Control Systems

A control system's primary function is to ensure stability and efficiency in processes by managing variables and inputs to achieve optimal performance.

Achievements Through Control Loops

Control loops enhance system performance, ensuring consistent operation, reducing variability, and achieving desired specifications effectively.
