There is provided a compressor ( 10 ) and an associated method for controlling a recirculation flow to control surging in the compressor. The compressor includes a housing ( 12 ) and a compressor wheel ( 16 ) mounted therein. A recirculation passage ( 41 ) receives compressed air from the compressor and recirculates the compressed air to an inlet passage ( 20 ) of the housing and, in particular, to leading edges ( 32 ) of blades ( 18 ) of the compressor wheel. An adjustable flow control device ( 60 ) is configured to control the flow of the compressed air through the recirculation passage to control a surge characteristic of the compressor. For example, the flow control device can include one or more valves (V 1 , V 2 , V 3 ), each of which can be adjusted by an actuator ( 64 ).
