This paper addresses fuzzy control systems, asymptotically stability analysis and fuzzy controllers design. A stabilizing control design method for nonlinear dynamical systems with uncertainties based on Takagi-Sugeno fuzzy models is discussed. The paper proposed asymptotic stability sufficient conditions for fuzzy control systems via Lyapunov’s second method.
We consider a nonlocal model of the wave process, which generalizes the classical model parmetricheskogo resonance Mathieu. It is proved that this model has a unique solution.
This work is devoted to developing algorithms for the solution of wave problems in mathematical physics on the basis of the boundary element method (BEM). The main advantages of the boundary element method is reduced to one dimension of the problem and transfer sample to the boundary of the study area, as well as obtaining a continuous solution in the region. As a consequence, reduces the amount of calculation and improves the accuracy of the solution.
Work is devoted research and development of methods of the analysis of model of regulation of multidimensional system. Using files of adjusting signs, procedure which allows to lower an order of an initial matrix of central parameters of system is constructed and to reduce a matrix of any order always to a matrix of the two-port network with the fixed poles of an input and a system exit.
We propose an algorithm for estimating the fractal dimension of time series of radon fields. Some regularities of the fractal dimension with the seismic activity in South Kamchatka.
Questions of a substantiation of application of methods of digital processing of signals are considered at the decision of problems of an active filtration of hindrances of the various nature arising in systems of an electrical supply. Traditional methods of suppression of pulse hindrances are analyzed, the application substantiation wavelet transformations for suppression of the pulse is spent.
The active seismic zone geophysical structure features and its models identification can be fixed by revealing planes on which the earthquake hypocenters are grouping. The algorithm and computer program are developed, to search the planes on the basis of the earthquake catalogue.
Determined by the orientation of the dislocations (normal vectors to the planes of discontinuities) vectors and shifts along the boundaries of dislocations According to Harvard directory (Global CMT catalog) for the period 1976 — 2005 years. for the zone subduction of the Kuril-Kamchatka island arc. According to the results of the statistical Data analysis aimed classified the type of distribution Binghama on the unit sphere, and the main characteristics distribution
The means of high precision calculation are considered, their comparative analysis isfulfilled, application of the most efficient of them for the geodynamo task is regardered.
