feedback
(foldoc) | feedback
Part of a system output presented at its input.
Feedback may be unintended. When used as a design feature,
the output is usually transformed by passive components which
attenuate it in some manner; the result is then presented at
the system input.
Feedback is positive or negative, depending on the sign with
which a positive change in the original input reappears after
transformation. Negative feedback was invented by Black to
stabilise vacuum tube amplifiers. The behaviour becomes
largely a function of the feedback transformation and only
minimally a function of factors such as transistor gain which
are imperfectly known.
Positive feedback can lead to instability; it finds wide
application in the construction of oscillators.
Feedback can be used to control a system, as in {feedback
control}.

feedback control
(foldoc) | feedback control
A control system which monitors its effect on
the system it is controlling and modifies its output
accordingly. For example, a thermostat has two inputs: the
desired temperature and the current temperature (the latter is
the feedback). The output of the thermostat changes so as to
try to equalise the two inputs.
Computer disk drives use feedback control to position the
read/write heads accurately on a recording track. Complex
systems such as the human body contain many feedback systems
that interact with each other; the homeostasis mechanisms that
control body temperature and acidity are good examples.
