feedback mechanism

Some output {feedback} can be input to regulate output [Wiener, 1947]. Feedback can compensate for minor departures from output level.

loop

Feedback loop continuously measures output {indicator, control}, modifies input {executive organ, control}, connects indicator and executive organ {transmitter, control}, and supplies energy {motor}. System parts {feedback mechanism} can subtract actual from intended output and send more or less signal to decrease differences, using algorithms {identification algorithm}.

setting

Feedback refines behavior but does not set behavior level, which is set manually.

signal

Too-great signals {overcompensation} cause cycles, as output overshoots intended output. Too-small signals {undercompensation} are not enough to overcome noise or inaccuracies and so fail to return system to expected performance.
