The composition and function of centrifugal compressor integrated control system are briefly introduced. The composition of anti-surge control strategy and their respective roles in anti-surge process are introduced, and the control of compressor performance Fundamentals and several basic ways to change compressor operating point position. The coupling relationship between performance control and anti-surge control is discussed. The decoupling conditions and the improvement of the compressor performance before and after the decoupling control algorithm are analyzed in detail.
