For the tasks decision of modes management by indirect parameters and the control of a state over the onboard equipment are offered new approximated forms of mathematical models for nonlinear dynamic objects. Offered models are based on the direct account of a static characteristics type of the objects received at bench test. The dynamic part of offered Hammershtein model is organized in the form of the astatic servo-mechanism, that provides increase of modelling accuracy and simplifies realization at preservation of a high-scale of adequacy. Comparison of modeling parameters of gas turbine engine with onboard registration data was executed.

Keywords: mathematical model, nonlinear object, management, dynamics computer realization.
