A Short Note on a Nonlinear System vibrations under Two Non-Ideal Excitations
(2003-10-01)
This paper describes a nonlinear phenomenon in the dynamical behavior of a nonlinear system under two non-ideal excitations: the self-synchronization of unbalanced direct current motors. The considered model is taken as a ...
Influence of ideal and non-ideal excitation sources on the dynamics of a nonlinear vibro-impact system
(2013-01-01)
The objective of the present work is to analyze the dynamics of a vibro-impact system consisting of two blocks of different mass coupled by a spring with two stages. Two different types of excitation sources for the system ...

On local analysis of oscillations of a non-ideal and non-linear mechanical model
(Kluwer Academic Publ, 2004-08-01)
It is of major importance to consider non-ideal energy sources in engineering problems. They act on an oscillating system and at the same time experience a reciprocal action from the system. Here, a non-ideal system is ...

On an Optimal Linear Control of a Chaotic Non-Ideal Duffing System
(Trans Tech Publications Ltd, 2012-01-01)
In this work, we use a nonlinear control based on Optimal Linear Control. We used as mathematical model a Duffing equation to model a supporting structure for an unbalanced rotating machine with limited power (non-ideal ...
On an Optimal Linear Control Applied to a Non-Ideal Load Transportation System, Modeled with Periodic Coefficients
(Trans Tech Publications Ltd, 2011-01-01)
In this paper, a load transportation system in platforms or suspended by cables is considered. It is a monorail device and is modelled as an inverted pendulum built on a car driven by a DC motor. The governing equations ...

A note on the attenuation of the sommerfeld effect of a non-ideal system taking into account a MR damper and the complete model of a DC motor
(Sage Publications Ltd, 2011-06-01)
The main purpose of this paper is to study the attenuation of the jump phenomena associated with the Sommerfeld Effect introduced by the nonlinearities of a magnetic rheological damper (MRD) in a non-ideal vibrational ...
Chaos control via Mathieu-Van der Pol system and Linear Optimal Control design with a non-ideal excitation and parametric uncertainties
(Scipedia S L, 2019-01-01)
In this work, a non-ideal system based on the Mathieu-Van der Pol System is modeled considering its parameters as uncertain, which makes it closer to reality. Numerical simulations are presented demonstrating that the ...
