Study of Fuzzy PID Control System for the Product Oil Pipe-Convey

Oil is one of the most important energy sources in the world, due to the uneven distribution of it, its transportation is an important step in the process of oil production. With the development of information technology, the traditional way of pipeline transportation has been unable to meet the requirement of high speed and high accuracy of product oil transportation process. A fuzzy PID control system in the product oil pipe-convey is designed in this paper, industrial control computer, programmable logic controller and KingView are used in the system for monitoring the oil transportation process on the computer. For the hysteresis character of pipeline pressure and oil flow rate, fuzzy PID is used in the system for reducing overshoot and improving control accuracy. Combined with programmable logic controller, KingView configuration software and fuzzy PID algorithm, the system has the advantages of easy operation, high reliability and easy upgrade. After put the system into production, the result shows that: the system has high reliability and high control accuracy, it can meet the requirements of the transmission of product oil.
