ABSTRACT:
A compressor surge control system is provided for a compressor system in which recirculation of gas from the discharge outlet of the compressor to the suction inlet of the compressor is utilized to prevent surging of the compressor. The recirculation of gas from the discharge outlet of the compressor to the suction inlet of the compressor is substantially minimized by using a first controller to provide a floating set point for a second controller. This reduced recirculation substantially increases the efficiency of the compressor system.
