Design of Nonlinear Multi-Mode Controller for Gas Turbine Engine in State Space Based on Algorithmic Approach

A gas turbine engine is a nonlinear and multi-mode dynamical control object. A synthesis of a nonlinear multi-mode gas turbine engine controller in a state space is considered. An algorithmic approach for the synthesis of a nonlinear multi-mode controller for a gas turbine engine the description of which is given in the form of a set of linear models for different modes of operation is proposed. The application of the constant eigenvectors of matrix-function, Grobner bases algorithmic approach and neural networks approximation of feedback control as an algorithmic basis for the synthesis of a controller is considered.

I. Introduction

In practice, for the control of multidimensional non-linear objects, the method of decentralized control has become widespread, in which the automatic control systems (ACSs) are divided into a number of separate (autonomous) subsystems, each of which measures a particular coordinate, comparing it with a setting value (command) and the development of a control action coming to the corresponding input of a complex technical object [1].
