An extraordinary fact about tbe human race has been that 'Man' was born as a 'Man-inventor and discoverer'. The history of the inventions done by man is no way less old than the history of man itself. Man has the ability to control his environments and their effect upon his life. Modern societies have developed efficient methods for heating and cooling to provide year-round comfort.
Jn the process of development, man produced machine and man himself was only necessary to control in detail the various perations that are required to complete any process. Slowly, the machines and the processes become more complicated. Also quick and accurate results were desired in most of the processes. Man became unable to perfectly control his own machine. It was in this context that it was tried to replace the human controller by same form of automatic controller which would precisely and speedily do what the man wants. The use of analog and digital computers has revolutionised the automatic control systems.
