TLDR
In this paper, a nonlinear formulation of the Moore-Greitzer rotating stall model is presented for control analysis and design, and the model is validated by comparing stall inception experiments to simulated stall inception transients.Abstract:
This paper presents a nonlinear formulation of the Moore-Greitzer rotating stall model that is suitable for control analysis and design. The model is validated by comparing stall inception experiments to simulated stall inception transients. The shape of the nonlinear compressor characteristic is shown to be a primary determinant of stall inception transient behavior. A Lyapunov stability analysis procedure is then presented. This procedure allows basins of attraction to be determined for various system operating points. Examples are given, and implications for design of rotating stall/surge control systems are discussed.read more

An overview of rotating stall and surge control for axial flow compressors
TL;DR: The objectives are to suppress rotating stall and surge, to extend the stable operating range of the compressor system, and to enlarge domains of attraction of stable equilibria using feedback control methods.

TL;DR: In this paper, an approximate theory for post-stall transients in multistage axial compression systems is presented, which leads to a set of three simultaneous nonlinear third-order partial differential equations for pressure rise, and average and disturbed values of flow coefficient, as functions of time and angle around the compressor.

Stall inception in axial flow compressors
TL;DR: In this article, the formation of finite amplitude rotating stall cells was investigated on two laboratory test compressors and it was shown that modal perturbations are not always present prior to stall, and when present, sometimes have little direct effect on the formation.
