Keywords: non-linear and linear mathematical model, control loop

In this paper a non-linear mathematical model of a low-power gas turbine, which is used in the Budapest University of Technology and Economics, will be presented. This topic is current, because with this model the manoeuvrerability of the engine can increase in special flight situations. According to the measurements, the parameters of the gas turbine are known, determined. The method of non-linear modelling is based on the thermodynamical equations, which describe the behaviour of the engine. With this model after linearization we can design an optimal controller for the gas turbine.
