Active Surge Control Of The Recycle Compression System By Hybrid Adaptive Controller
Résumé: Centrifugal compressors are a Type of widely used compression systems for industrial gases. Practically, centrifugal and axial compressors often suffer huge and irreversible damages due to a major non-stability feature widely known as surge. In this paper, a control strategy is proposed in order to avoid falling into surge and to recover the system from deep surge state. An auto-tuned, PID-Based, model free approach based on Multi-stage Fuzzy Inference system is used to provide a real-time tuning for PID parameters in order to achieve optimal control for the Compression system’s recycle valve. The proposed control solution comes to prevent the system from falling into surge and shows promising results while recovering the system back into stability and maintaining stable operating point. Furthermore, a stable and robust, model free control, has been achieved for deep surge control
