Review of Automatic Control Systems and Their Types

Abstract

Automatic control applies to the system applications of control theory for carrying out
several sets of processes together without any role of humans or human interference. In any
simplest type of control loop a controller is set to measure the desired process values. Such a
closed loop control system is just how a negative feedback system is applied in a system. And
designing of such an automatic controlling system requires addition of feed in the form of
electrical energy for enhancing features of disturbed or errant system. And the feed in the
form of electrical energy is regulated for implementing automatic control to the system with a
set of or several devices.
