Performance evaluation of compressor anti-surge control based on model predictive in ammonia plant

Surge is major problem in compression system especially in process industries. Typically, surge can be eliminated by providing the compressor anti-surge controller based on proportional integral derivative (PID) control or model predictive control (MPC). This study designed and evaluated the performance of MPC at centrifugal compressor in ammonia plant. The MPC is compared with the existing and tuned PID control. The evaluation results show that the performance of designed MPC is better than PID control for compressor anti-surge control in ammonia plant.
