Boudiba O. The functionally steady system of stabilization and orientation the small-sized aircraft

Object of research – processes of control systems operation and navigation of small-sized unmanned aerial vehicles (UAV); the aim of research – to improve the system of orientation and stabilization of small-sized aircraft in emergency situations by providing two-level functionally stable control; research methods - methods of theory of automatic control, the theory of fault-tolerant systems, the theory of complex systems, the theory of sets, graph theory, technical diagnostics, theory of algorithms; novelty – the method of determining the parameters configuration control aerodynamic surfaces based on aircraft performance criteria has been development, that enables to provide functionally stable control of small-sized UAV both in nominal mode and in the event of extraordinary situations; the model of small-sized UAV control system has been improved by the impact of changes in the aerodynamic characteristics of the appearance of abnormal situations, enabling real-time to ensure a sustainable stabilization and orientation of the device; further development of the method of situational parry an extraordinary situation in the direction of the two-level redundancy has been taken, that ensures stable motion control functionality of small-sized UAV on the results of diagnosis of the situation; results – got the basis for the creation of two-level functional-stable navigation and control systems of small-sized UAV, which allows to increase significantly the functional stability of both existing small-sized unmanned systems and those that are being projected; the degree of implementation – have been implemented in the SPE “HARTRON-ARKOS”, in the LLC "Research center of civil projects", in the National Aerospace University "KhAI"; the field of use – small-sized UAV control systems.
