HISTORY OF CONTROL SYSTEMS

History - Water Clock

One of the earliest control systems known is the water clock invented by Ktesibios (300 BC).

CONTROL SYSTEMS BASICS

Primary Aim of Control system:

-? To regulate certain variables about constant values even when there are disturbances.

-? To force some parameter to vary in a specific manner.

Control Methods:

-? Manual control
-? Automatic control

Classifications of control systems
