Cooperative control of centrifugal compressor´s flow and pressure

In this paper a cooperative control method of centrifugal compressor´s flow and pressure is proposed. Base on the analysis of the inherent characteristic of centrifugal compressor and the response time of actuators, a cooperative control strategy is obtained. This control strategy can adjust the flow´s and pressure´s trajectory in time which let the operating point of centrifugal compressor change smoothly. Simulation results show that the proposed method can change the operating point of centrifugal compressor smoothly in the process of adjusting flow and pressure.
