Online Monitoring and Control of Flow rate in Oil Pipelines Transportation System by using PLC based Fuzzy‐PID Controller

Along with the development of urban construction and industrial requirements, more and more long distance oil pipelines have built and served. For this, the industries require more reliable, robust, efficient and flexible control system for the automation in oil pipeline system to prevent leakages during transportation. In this paper, a new PLC based Fuzzy-PID controller is designed to automatically regulate the flowrate of the petroleum products at destination by controlling the multiple pressure signals range in the long transmitting concrete pipes. The performance of the Fuzzy-PID controller is compared with the PLC based Cascade-PID controller. The developed PLC based Fuzzy and Cascade-PID controllers are implemented for the lab scale experimental setup and their performance analyses are verified experimentally. The real time data of pressure and flow are monitored through SCADA screen used to provide instantaneous trends using data logging. From the real time experimental results, it is inferred that Fuzzy-PID controller provides most superior performance with minimum time delay as compared to Cascade-PID controller on upholding flow at specified range by implanting multiple pressures as manipulated parameters.
