Research on Fuzzy Control of Centrifugal Compressor Anti-surge in Long-distance Natural Gas Pipeline

Now, the demand for natural gas in all walks of life is increasing. Our country has built a large number of natural gas pipelines. The centrifugal compressor is of great significance to the smooth operation of the natural gas pipeline network. Surge is a dangerous working condition that may occur when the compressor is running, although traditional anti-surge solutions guaranteed basic operational safety, the control effect still has a large amount of rooms for improvement. This paper designs an anti-surge controller based on fuzzy theory and validates it by simulation.
