Wm. Haddad et al., Nonlinear robust disturbance rejection controllers for rotating stall and surge in axial flow compressors, IEEE CON SY, 7(3), 1999, pp. 391-398
In this paper we develop globally stabilizing robust/disturbance rejection
controllers for rotating stall and surge in axial flow compressors with unc
ertain system dynamics and exogenous disturbances. Specifically, using the
nonlinear-nonquadratic disturbance rejection optimal control framework for
systems with bounded energy (square-integrable) L-2 disturbances developed
in [15] and the nonlinear-nonquadratic robust optimal control framework for
systems with nonlinear structured parametric uncertainty developed in [16]
, a family of globally robustly stabilizing controllers for jet engine comp
ression systems is developed. The proposed controllers are compared with th
e locally stabilizing bifurcation-based controllers of [17]-[20] and the re
cursive backstepping controllers of [21].
