Zhukovsky "Kharkiv Aviation Institute" popup.description2 In work the elaboration's result of the fault-tolerant control systems projection theory in aerospace branch are presented. The purpose of development is the creation of modern concept, analytical and computer methods of projection of fault-tolerant control systems ensuring the required level of flight vehicles safety. Methods of the researches are mathematical, half-full-scale modelling. During of work the analysis of existing methods of security of fault tolerance as a point of view of possibble formalization of fault-tolerant control system projection process was conducted. The methods of diagnosing and recovery of functionability giving in formalization and permitting for ensuring a required level of flight vehicle safety were selected. The selected methods were supplemented by a new tool - hierarchy of diagnostic models permitting to formalize process of diagnosing and the analysis of diagnostic properties of a control system. For solving of functionability recovery problem the technique of re covery algorithms construction was developed. The technique actuates discriminatory analysises of available resources which can be used in this or that unnominal situation, principles of their joining in a hierarchy and models of flexible recovery. The offered techniques were checked up while development of fault-tolerant onboard measuring devices and also control system of a pilotless flight vehicle steady against damages of a glider. Area of outcomes application- control system design of aerospace branch objects. Product Description popup.authors popup.nrat_date 2020-04-03 Close
