A simplified model of gas turbine unit adaptive control

The article explores the possibilities of building automatic control systems for gas turbine power plants. The use of the principles of adaptive control with a reference model and a signal effect is being studied. As an adaptation method, a method based on the Lyapunov function is used, in order to reduce the time for searching for an extremum. There is a need to ensure the specified indicators of electricity the quality in a constantly changing electrical load and changes in operating modes of the power plant in gas turbine units. The article presents a model of a gas turbine installation for the study of adaptive control. It is shown that the improvement of one coordinate is possible to obtain due to some deterioration of the other coordinate. For further study of this problem, a simplified second-order dynamic model has been constructed. With the help of such a model, complex studies of various stages of adaptive control were carried out. Results were obtained by varying the parameters of adaptive control and simulation parameters. The research results are designed to find the optimal ratios of adaptive automatic control systems parameters for power industry gas turbine plants.
