This paper presents a new fuzzy control approach to compressor surge control. A variable area throttle is used in this strategy. The controller uses measurements of flow and the change of flow to determine the control action. By using the change of mass flow, 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 model of the controlled compressor and it works on any compressor as long as the static stability criterion is satisfied. The fuzzy rules are transferable and only the scaling factor and the throttle capacities 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.
