automatic feedback control system
Quick Summary
Automatic feedback control systems are a fundamental component of automation. These systems use a closed-loop process to maintain a desired output by continuously monitoring and adjusting based on feedback.
A feedback control system has five key parts:
* Input: The desired value or set point.
* Process: The system being controlled (e.g., a heater).
* Output: The variable being measured (e.g., room temperature).
* Sensing Elements: Devices that measure the output.
* Controller and Actuating Devices: These compare the output to the input and make adjustments to the process.
This allows automated systems to self-regulate and maintain specific operating conditions, a concept with historical roots dating back to Roman engineers and James Watt's flyball governor.12
