Closed loop gain이란

WebIn a closed loop system, the transfer function defines the mathematical relationship between the input and the output. The change on the output by the input or the relationship between the detected sensor value is known as the gain of the system. WebA closed loop control system is a mechanical or electronic device that automatically regulates a system to maintain a desired state or set point without human interaction. It …
