Nonlinear model-building of a low-power gas turbine

Abstract

The development of a nonlinear gas turbine model is presented in this paper for loop-shaping control purposes. The nonlinear dynamic equations of the gas turbine are based on the first engineering principles. In order to complete the model, constitutive algebraic equations are also needed. These equations describe the static behavior of the gas turbine at various operating points. The complete, substituted nonlinear model is presented along with its model verification results based on a simulator and measured data.
