摘要

A new adaptive modeling method for aircraft engine by using equilibrium manifold (EM) and its expansion (EME) model is presented, following research undertaken by the authors at School of Transportation Science and Engineering, Beijing University of Aeronautics and Astronautics, Beijing, China. The property of the expansion model and the effect of mapping design to the form are systematically studied. The model adaptivity analysis is discussed, and this paper also gives the identification procedure of modeling the aircraft engine approximate nonlinear model; the deterioration modification of compressor and the comparison with linear parameter-varying model and Kalman estimator are discussed. Simulations illustrate that modeling accuracy is high and the structure is simpler.
