摘要

In this paper, we analyze the mutual relationship among parameters in the anti-surge controlling process of centrifugal air compressor; build time-varying system of air compressor for anti-surge; put forward generalized predictive control method based on cascade control; and apply to the governing system which separates the deep and cold air for a certain chemical plant. The results showed that this controlling method can restrain the interferences from uncertain things and harmful effects on the system coming from nonlinearity factors, and can prevent effectively the occurrence of surge phenomena.
