feedback control
Quick Summary
Feedback control is a system where part of the output is fed back as new input to modify and improve subsequent output. In electronics, this is often used to stabilize circuits or perform other functions. A common type is negative feedback, where the feedback signal opposes the original signal, reducing overall gain but correcting distortions.123
Feedback control systems, also known as closed-loop systems, consist of an input (desired value), a process, an output (measured value), sensing elements, and a controller. The controller compares the measured output to the desired input and makes adjustments to reduce any difference. This principle is fundamental to automation, enabling systems to self-correct and maintain desired operating conditions.45
