    PID and Novel Approach of PI Fuzzy Logic Controllers for Active Surge in Centrifugal Compressor
    (Springer, 2013) Chetate, Boukhmis; Zamoum, R.; Fegriche, A.; Boummdine, Mohand Said
    The operating range of aerodynamic compressors is usually limited by a phenomenon known as surge. Active surge control has showed the ability to extend the operating range significantly. This study presents a solution to this problem based on classical PID regulator and a new PI fuzzy logic approach with three lines of protection. The fuzzy controller is designed to avoid the surge instability on a given compressormodel. Simulation studies showpromising results at different operating points compared to the results obtained using PID controller
