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
Based on the purpose of the system and the relevant classes it belongs to
MATLAB
-? Important tool in current control system design.
-? Recall:
-? To achieve:
PO4: Ability to work with modern instrumentation, software and hardware.
through:
CO4: Apply MATLAB software in analyzing control system performance
-? MATLAB contains:
-? Lots of Toolboxes - one of them is ‘Control System Toolbox'
-? Simulink - click and drag
