Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Formation of Algorithmic Support for a Promising Flight and Navigation Complex Based on the Concept of Dynamic System Synthesis M.S. SELEZNEVA The algorithmic support of the sighting and navigation complex of a highly maneuverable aircraft has been studied. The algorithms of estimation, control, identifi cation and construction of models as part of the algorithmic support used for the correction of navigation systems and complexes are considered. It is proposed to automatically generate in flight error models of navigation systems with improved quality characteristics of observability, controllability and parametric identifiability. Numerical criteria for the degree of observability, controllability, and parametric identifi ability are considered, as well as a method for controlling these criteria when forming ensembles of selection of selforganization algorithms. Functional schemes of algorithms are developed and their features are discussed. Keywords: aircraft, sighting and navigation system, dynamic system synthesis, qualitative criteria, self-organization, selection ensemble, redundant trends. DOI: 10.25791/pribor.4.2023.1400 Pp. 10-14.
