Abstract

The linearization of a nonlinear system may be uncontrollable at a desired operating point when all points in a neighborhood of the operating point are controllable, The Moore-Greitzer model (1986) of rotating stall in a jet engine is such a problem and is studied here. Model validation techniques are used to evaluate a model linearized about a perturbed operating point, and including unknown bounded perturbations. Such models are well suited to robust control design techniques
