Automation is the optimization of production systems and process through the application of computerized systems. Automated systems today find use in many areas where processes can be computerized such as in the industrial assembly lines. Control engineering deals with application of the principles of control theory in the control of systems and this is automatic control. Control engineering finds application in virtually any system that involves some control whether in industrial production in the laboratory or at the household level. These disciplines cover diverse fields such as information technology, cybernetics, automation, artificial intelligence and robotics.
