Enhancement of water level control system (software development) / Hairol Jaffar

Automatic Control System has played a vital role in the advance of engineering and science. In addition to its extreme importance in space-vehicle systems, misslile guidance system, air-craft-autopiloting systems, robotics systems and the like, automatic control has become an important and integral part of modem manufacturing and industrial operations as controlling pressure, tempureture humidity, viscosity, flow in process industries and controlling liquid in specific tank. Since advances in the theory and practice of automatic control provide the means for attaining optimal performance of dynamics system, improving productivity, relieving the drudgery of many routine repetitive manual operations, and more, most engineers and scientists must now have a good understanding of this field. For this thesis, the main objective is to make the system in the plant fully controlled by computer. Thus the computer is now easy to use and available in the low cost of price, its become one of the powerful tool in control system applications. The PC will be a major element in this project and supported by PCL-812PG card as a interfacing card and Turbo C as a programming language in this application. All the setting and theory are provided in this thesis.
