This project deals with a number of facts related to the output
feedback stabilization of the Moore-Greitzer compressor model. We show
that quadratic feedback stabilization of the surge subsystem of
the three-state Moore-Greitzer compressor model, which ensures an
absence of additional equilibria in the augmented with stall
dynamics closed loop system, implies convergence of all solutions to
the unique equilibrium at the origin. Then some steps in
developing such output feedback controller for surge subsystem are
discussed, and a family of controllers is presented. Based on our
new theoretical results on integrability, stability, nonlinear dynamic
output feedback control, we wish to pursue active control
application to compressor systems and experimental verification.
