The path of blade flow in the course of oscillation used to be first followed because the keep watch over parameter, since it was once identified to be a rather influential issue for vibration instability of blades within the transonic flows. the strategy may reduce the passage surprise circulation close to the blade floor and successfully suppress the blade vibration, although it was once no longer potent whilst the blade stiffness used to be small. For more advantageous regulate, the strategy during which the trailing fringe of blade used to be actively vibrated was once sought to manage the passage surprise oscillation. The trailing facet oscillation should be learned by way of, for example, program of piezo-electric equipment. the tactic used to be printed to alter the unsteady aerodynamic strength acted at the blade from intriguing to damping strength if the part of trailing area oscillation was once appropriately chosen. The suppressing impression of the keep an eye on approach got here from its impact on passage surprise stream, which used to be confirmed via built flow-structure coupled procedure. creation energetic keep an eye on of surge and rotating stall has been effectively studied within the final decade [1] together with phenomenological description of the onset of instability and regulate mechanism.
