Method And Device Performing Model Based Anti Surge Dead Time Compensation

Abstract: Methods (400) and devices (140, 150) for performing a model based anti¬surge dead time compensation in systems (100) including a compressor (110) and an anti-surge loop (120) are provided. A new position of an anti-surge valve (130) on the anti-surge loop (120) is determined by correcting for dead time a value of the anti-surge parameter calculated from field measurements, based on a predicted anti¬surge parameter estimated using a deterministic model which has as variables the field measurements and a current position of the anti-surge valve (130).
