Resonances in nonstationary, nonlinear, multidegree-of-freedom systems
13th Structures, Structural Dynamics, and Materials Conference, 1972The asymptotic method for determining resonant responses of nonstationary , nonlinear systems is presented. Resonance conditions, resonance coefficients, and higher-order resonances are discussed. The first asymptotic approximation nonstationary solution is obtained for general resonances.

Solvability of a nonlinear nonstationary system of equations
Lithuanian Mathematical Journal, 1990The initial-boundary value problem for a system \[ \begin{gathered} \partial u_ k/\partial t=ia_ k\Delta u_ k+f_ k(u,\bar u),\;k=1,...,r; \\ \partial u_ k/\partial t+ib_ k\partial^ 2u_ k/\partial t^ 2=ia_ k\Delta u_ k+f_ k(u,\bar u),\;k=r+1,...,m \end{gathered} \] on a bounded domain \((0,T)\times\Omega\) is examined.

Nonstationary equivalent linearization of nonlinear continuous systems
Probabilistic Engineering Mechanics, 1993Abstract This paper presents a technique for obtaining the nonstationary stochastic response of a nonlinear continuous system. The method of equivalent linearization is generalized to continuous systems subjected to nonstationary random excitation.

Structural rules for the determination of sensitivity functions of nonlinear nonstationary systems
IFAC Proceedings Volumes, 1964Publisher Summary This chapter discusses the structural rules for the determination of sensitivity functions of nonlinear nonstationary systems. The structural methods proposed for sensitivity analysis of linear stationary and certain nonlinear systems are more practical than the purely analytical procedures, although the latter are considerably more

Stability of Nonlinear Systems with Periodically Nonstationary Linear Part
Zeitschrift für Analysis und ihre Anwendungen, 1991Multidimensional nonlinear systems with periodically nonstationary linear part are considered. It is supposed that nonlinear blocks satisfy some integral quadratic constraint. The necessary and sufficient condition of absolute stability with respect to output for such systems are established in terms of certain properties of solutions of a linear ...

ALGORITHM FOR ADAPTIVE ESTIMATION OF PARAMETERS FOR NONLINEAR NONSTATIONARY SYSTEMS
ВЕСТНИК ВОРОНЕЖСКОГО ГОСУДАРСТВЕННОГО ТЕХНИЧЕСКОГО УНИВЕРСИТЕТА, 2023рассматривается задача оценивания неизвестных параметров для класса нелинейных нестационарных систем. В этом случае предполагается, что матрица состояния системы содержит неизвестные нестационарные параметры. Допустим, что нестационарные параметры системы могут быть представлены как выходы линейных генераторов с неизвестными матрицей состояния и ...
