Anti-surge switching control of centrifugal compressor based on control performance assessment

Switching control is a basic anti-surge control strategy for compressor, according to the problem that the switching point is mainly chosen by human experience, this paper presents a method that can determine the anti-surge point automatically. This paper uses the Generalized Minimum Variance (GMV) benchmark to assess the performance of control systems, by monitoring the performance changes of anti-surge control system, and according to the relationship of anti-surge technological requirements and the control performance index, it can automatically calculate the switching point of anti-suge control. The simulation results show that the method has effective and practical characters.
