Graf M. Models and information technologies of information processing in an unmanned aerial vehicle

The object of the research is the process of information processing in the on-board computer of the UAV. The subject of the research is methods, mathematical models and algorithms for processing information in an on-board computer of an unmanned aircraft. In the presented dissertation work, a scientific and applied problem is solved to improve the accuracy, speed and reliability of information processing during transmission in UAV communication systems, possible control operations are considered, it is proposed to use an approach for deriving solutions based on a logical-linguistic model and using neural networks ones. The solution to this problem is carried out by the development of information technology, methods, techniques and software applications, with the help of which the prerequisites are created to improve the quality of the results, planning and redevelopment of the trajectory of the UAV or RPAS in a static and dynamic environment with avoiding obstacles. In the dissertation work, for the first time, developed information technology for information processing in UAV systems; for the first time it is proposed to use the method of information processing in the control of UAV using a combination of neural networks; for the first time developed a new method of information processing in the construction of the flight path of the UAV; for the first time a new mathematical model for processing information and computer systems of the control unit is proposed. The information technology of determination of coordinates of obstacles in the static environment and reorganization of a trajectory of flight of UAV at change of coordinates in the dynamic environment has received the further development. The proposed information technology can be used in systems of intellectual information processing in the aviation industry, in particular in the airports of Ukraine. The structure of the modernized multilevel control system has been improved. The synthesis of the decision-making system in the computerized control system of the unmanned aircraft is carried out.
