Prosvirin D. Quality improvement of regional aircraft automatic control at approach phase under disturbances conditions

The dissertation is devoted to the creation of a model, methods, algorithms for controlling the flight of a regional aircraft during approach, which allows to improve the quality of automatic control, efficiency of energy resources of the aircraft in disturbances. As a result of the conducted researches the actual scientific task of development of methods, models of control of the regional plane which use the information of data on object of management for increase of quality and efficiency of flights is solved. The purpose of the work is to increase the efficiency of energy use of the regional aircraft by creating an automatic control system (ACS) at approach phase. To achieve this goal in the work were set and solved the following tasks: 1) analysis, refinement and improvement of existing approaches and methods of aircraft control; 2) development of algorithms for optimal flight control of a regional aircraft during approach phase; 3) development of a model of AFCS by flight of a regional aircraft at approach phase (development of software and mathematical control complex, databases of flight technical data; conducting semi-natural tests for selection of coefficients of control laws); 4) development of flight control technology for a regional aircraft at approach phase on the basis of the proposed control method and ACS model, which provides effective aircraft control with minimal crew participation. 5) implementation and production testing of results. An adaptive model of the automatic flight control system of a regional aircraft at approach phase has been developed, which differs in the use of high-precision flight technical data that provide calculation and execution of optimal flight in terms of fuel consumption at disturbances conditions. Algorithms for optimal flight control of a regional aircraft during approach phase are developed, which uses new solutions for the approach method, which ensure the implementation of procedures with minimal fuel costs Implementation of information technology for flight control of a regional aircraft saves around 50% of fuel costs.
