    ADAPTIVE ROBUST CONTROL OF MULTIVARIABLE STATIC PLANTS WITH POSSIBLY SINGULAR TRANSFER MATRIX
    (ВД "Освіта України", 2013) Azarskov, V. N.; Zhiteckii, L. S.; Solovchuk, K. Yu.
    A new problem of the adaptive robust control of linear discrete-time multivariable static plants with the singular transfer matrices in the presence of bounded disturbances is stated and solved. The asymptotical properties of the adaptive robust feedback control systems designed via the proposed method are established

    SEQUENTIAL LEARNING PROCESSES IN NEURAL NETWORKS APPLIED AS MODELS OF NONLINEAR SYSTEMS
    (ВД "Освіта України", 2013-10) Azarskov, V. N.; Zhiteckii, L. S.; Nikolaienko, S. A.
    Asymptotic properties of the online gradient algorithm with a constant step size employed for learning in neural network models of nonlinear systems having one hidden layer are examined. Some conditions guaranteeing the convergence of this algorithm are established.

    VIBRATION DAMPING FOR THE PROBLEMS OF AIRCRAFT MOTION
    (ВД "Освіта України", 2014) Azarskov, V. N.; Gristchak, D. D.
    Two-step hybrid asymptotic method based on perturbation methods and phase integrals (me- thod WKB) is used to obtain approximate analytical solutions of the nonlinear problem of the vibrations of the aircraft near the rough surface, which reduces the need for the integration of singular nonlinear dif- ferential equation with time-variable periodic coefficients for given initial conditions. This solution is not limited to the value of the dimensionless amplitude of perturbations and the nature of the order non-linear restoring force. The resulting solution has the form of the sum, where each term consists of two functions according to the method of perturbation (in scalar parameter when the nonlinear component of the original equation) and the WKB-approximation, effective in the integration of singular differential equations with variable coefficients. For specific numerical results, a comparison with the data of direct numerical inte- gration of the equations of the original problem
