Compressor surge control using a variable area throttle and fuzzy logic control

Lookup NU author(s): Salim Al-Mawali, Dr Jie ZhangORCiD



In this paper we present a new fuzzy control approach to compressor surge control. A variable area throttle is used in this strategy. The controller uses measurements of the mass flow rate and the change of mass flow rate to determine the control action. By using the change of mass flow rate, the controller does not need to know where the operating point is. One advantage of the proposed controller is that it does not need a mathematical model of the controlled compressor and it works on any centrifugal compressors. The fuzzy rules are transferable and only the scaling factor and the throttle capacity need to be changed when the controller is applied to another compressor of the same type. Simulation results show that the proposed controller gives good performance in various situations.
