Abstract
The centrifugal compressor converting the kinetic energy into the pressure increase has been extensively used for industry applications. Due to its high rotational speed, the volume and weight could be greatly reduced which makes it suitable for in-flight gas compression systems. Combining the high altitude circumstances such as the air density, pressure, temperature, etc., an centrifugal compressor model is first developed in this paper. This model takes the changing properties of the atmosphere, air pressure and air density into account. The working characteristics of the centrifugal compressor at different altitudes are studied. Meanwhile, the effects of the parameter variations on the compressor performance is analyzed. Moreover, dynamics of the air flow and pressure are investigated with varied altitude. A closed loop controller based on super twisting sliding mode approach is proposed to make the mass flow track the reference.
