Control systems play a critical role in space flight. Control engineering or control systems engineering or Automation engineering (In Some European Countries) is an engineering discipline that deals with control systems, applying control theory to design equipment and systems with desired behaviors in control environments.

In computer security, general access control includes identification, authorization, authentication, access approval, and audit.A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject, based on what the subject is authorized to access.
The definition of a closed loop control system according to the British Standards Institution is "a control system possessing monitoring feedback, the deviation signal formed as a result of this feedback being used to control the action of a final control element in such a way as to tend to reduce the deviation to zero."
In control theory, an open-loop controller, also called a non-feedback controller, is a control loop part of a control system in which the control action ("input" to the system [1]) is independent of the "process output", which is the process variable that is being controlled. [2]

Components of an access control system include: An access control panel (also known as a controller) An access-controlled entry, such as a door, turnstile, parking gate, elevator, or other physical barrier; A reader installed near the entry. (In cases where the exit is also controlled, a second reader is used on the opposite side of the entry.)
From the early 1980s when SPAWARs PD-40 VADM Jerry O. Tuttle's Joint Operations Tactical System was the premier system, through the tenure of RADM John Gauss's Joint Maritime Command Information System (JMCIS), the final product would be realized as the Global Command and Control System (GCCS), introduced conceptually by the Defense Information ...
