Application of Fuzzy PID in Pressure Control of Airport Pipeline Refueling System

摘要

The pressure is the most important parameter in the process of airport pipeline refueling. But it is difficult to control the pressure because of nonlinearity and time delay of a pipeline refueling system. In this paper, the properties of airport pipeline refueling system were studied and a pressure control method based on fuzzy PID controlling algorithm was put forward. The control method with the pressure forecast of the pipeline outlet can make up for nonlinearity and time delay of pipeline refueling system and proved to be useful for improving stability of airport pipeline refueling pressure.
