Abstract :

The range of operation of compressors is limited by the surge phenomenon. Surge control is inevitable to deal with this phenomenon. In this paper, a solution to control it with a fuzzy controller using a surge control line and a surge line using a remote control. The speed of the compressor is also expressed using the anti-surge valve (in combination). A fuzzy controller is designed to stop the surge according to the compressor model with a high degree of safety. Simulations show the use of these simple controllers compared to classical controllers and their efficiency.
