Surge in centrifugal compressor is flow stable oscillation with a large-amplitude. Since it decreases performance and even may damage the compressor, surge is highly undesired in compressor operation. To overcome the surge problem, two common methods applied are surge avoidance and active surge control. The last mentioned method seem more promising since it can extend the compressor operation range. In this paper, we present self-tuning fuzzy (STF) controller as an approach on active surge control method. The controller consists of two level of fuzzy controllers. The first level controller acts as the plant controller, while the second one provides parameter tuning of the first level controller. By simulations, we demonstrate that STF can manage the compressor operation from getting surge in several reference points in the surge region.
