A four-degree-of-freedom model able to capture the main phenomena which are likely to occur in the non-planar finite dynamics of an elastic suspended cable subjected to external forcings and support motions is developed from the continuum equations. It contains two in-plane and two out-of-plane comp

β¦ Synopsis
A norm-bounded locally optimal control is constructed which minimizes the frequency and phase deviations from resonance in a non-linear system affected by bounded perturbations. It is shown that this control is independent of the form of the perturbation and the structure of the conservative part of the system. As an example, frequency and phase controls of forced oscillations in a system of two weakly coupled oscillators are constructed.

The motion of an autonomous Hamiltonian system with two degrees of freedom near its equilibrium position is considered. It is assumed that, in a certain region of the equilibrium position, the Hamiltonian is an analytic and sign-definite function, while the frequencies of linear oscillations satisfy
Given a deterministic controlled system (in continuous time or in discrete time), we assume that we have computed a feedback control which stabilizes the system. We show that the system remains exponentially stable under some stochastic perturbations of the applied control and of the system equation
The transient response of a single-degree-of-freedom oscillator with a slow-variant natural frequency and a small non-linear damping is under consideration. The damping is modelled as a sum of elementary power functions with respect to the system velocity. The passage through a resonance which is in
