Control engineering

A power-amplifying loop that makes output follow a command

A servomechanism is a feedback control system whose job is to make a physical output (position, speed, or orientation) follow a commanded reference, using error between command and measured output to drive a power-amplifying actuator. Hazen's 1934 Theory of Servo-mechanisms gave the early systematic account of such error-actuated, power-amplifying loops and their response to inputs. The referent is a class of command-following feedback systems, judged by how faithfully and quickly the output tracks the reference, and it anchors the position- and motion-control corner of the control map.[1]

Unit
The tracking error between commanded reference and measured output
Recovery means
Not applicable
Measured by
Assessed by tracking accuracy, steady-state error to reference inputs, and the speed and damping of the transient response
