Abstract

Abstract:

Modeling method with two step is proposed according to the characteristic of the expansion model. Modeling of nonlinear system is translated to static parameter fitting and dynamic identification with leastsquare method, and the validation of the method is demonstrated by identification of turbojet engine with one shaft.

Key words: turbojet , engine, , equilibrium , manifold, , identification, , least-square
