Line 18:

Likewise, a "'Feedback Control System' is a system which tends to maintain a prescribed relationship of one system variable to another by comparing functions of these variables and using the difference as a means of control."<ref>{{cite book|title= The Origins of Feedback Control|last=Mayr|first= Otto|year= 1969|publisher =The Colonial Press, Inc.|___location= Clinton, MA USA|isbn= |pages=}}</ref>

The advanced type of automation that revolutionized manufacturing, aircraft, communications and other industries, is feedback control, which is usually ''continuous'' and involves taking measurements using a [[sensor]] and making calculated adjustments to keep the measured variable within a set range.<ref>Bennett, Stuart (1992). A history of control engineering, 1930-1955. IET. p. p. 48. {{ISBN |978-0-86341-299-8}}.</ref> The theoretical basis of closed loop automation is the discipline of [[control theory]].
