Zhezhera I. Models and methods for ensuring the functional stability of an autonomous small-sized aircraft measuring subsystems

Object of study - the processes of autonomous small-sized aircraft control systems operation and navigation; the purpose of the research is to ensure the functional stability of the autonomous small-sized aircraft measuring subsystems by using interchannel redundancy and deep diagnosis with subsequent flexible restoration of parameters according to the visual information; research methods - fault-tolerant systems theory, principles and methods of system analysis, signal-parametric approach for diagnosing technical systems and computer vision methods for calculating excess information on visual data; results - models and methods for ensuring the functional stability of the autonomous small-sized aircraft measuring subsystems; academic novelty - for the first time the spatial parameters restoration method of the autonomous small aircraft measuring subsystems, which, unlike the existing methods, provides the functional stability of the measuring subsystems of an autonomous small aircraft with the required accuracy in the emergence of extra-dimensional situations with use of computational computer vision, inertional and satellite navigation data; the method of MEMS sensors diagnosing to the level of determining the type of emergence situation due to the changing of diagnostic models and creating redundancy structure, combining the existing sensors to complementary units with the quantity n + 2, which made it possible to obtain reliable parameters of the spatial position of the autonomous small-sized aircraft in real time; further developed the method of ensuring the functional stability of the measurement subsystems due to the use of developed redundant sources of information models, which, unlike the existing methods, made it possible to ensure the stable functioning of the measurement subsystems in real time; degree of implementation - results were implemented in the research and production enterprise "HARTRON-ARKOS", in the research and production enterprise "Terraviatech" and in the Limited Liability Company MAVA Technologies; field of application - control systems of small UAVs.
