Passivity Based Surge Control,In this chapter passivity will be used to derive a surge controller for a compression system when time varying disturbances are considered in both pressure as well as mass flow.

A Moore-Greitzer Type Model for Axial Compressors with Non-Constant Speed,In this Chapter we propose an extension to the Moore-Greitzer model, where non-constant rotational speed of the compressor is taken into account. The consequence of this is that the new model includes the B-parameter as a state. Higher harmonics of rotating stall will also be included in the model.

Stratified Groups and Sub-Laplacians, this approach will be used also for rotating stall control. When using the throttle as an actuator for rotating stall control, the . to the left of the surge line can be stabilized and the bifurcation is changed from subcritical to supercritical, elliminating the hysteresis. On the other hand, it
