Алгоритм построения областей устойчивого функционирования системы управления ЛА

Abstract

Problem of definition of estimation of regions of stable functioning of flyings vehicles (FVs) in presence of partial failures on the basis of given dynamic properties is important issue. Failures by variation of parameters of FV control system are introduced into system. We build area providing for first difference fulfilment of condition for initial system and system with failures into which surface v = C defining estimation of region of attraction is inscribed. The region of attraction at failures decreases so that it corresponds to deterioration of properties of initial system. At these failures we carry out search of Lyapunov function allowing to construct the region of stability close to initial or greater than initial.
