TL;DR: In this article, a transonic single-stage axial compressor using active feedback control was used to stabilize the first and second spatial harmonics of the prestall perturbations using constant gain feedback.

TL;DR: In this article, micro-flow control actuation embedded in a stator vane was used to successfully control separation and improve near stall performance in a multistage compressor rig at NASA Glenn.

TL;DR: In this paper, the authors presented the first attempt to stabilize rotating stall in a single-stage transonic axial flow compressor with inlet distortion using active feedback control using forced response testing and to extend the compressor stable operating range.

TL;DR: The potential for using endwall recirculating to increase the stability of transonic highly-loaded multistage compressors is demonstrated through results from a rig test of simulated recirculation driving both a steady injected flow and an unsteady injected flow commanded by closed-loop active control during compressor operation at 78–100% of design speed.
