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 ...
Control design applied to a non-ideal structural system with behavior chaotic
(2013-08-09)
In this paper we study the behavior of a structure vulnerable to excessive vibrations caused by an non-ideal power source. To perform this study, the mathematical model is proposed, derive the equations of motion for a ...

Comments on a nonlinear and nonideal electromechanical damping vibration absorber, Sommerfeld effect and energy transfer
(Springer, 2009-01-01)
In this paper, we investigated the effectiveness of the linear electromechanical vibration absorber (LEVA) and a nonlinear electromechanical vibration absorber (NEVA) in the vibration attenuation for nonideal structures ...

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 Lugre Friction Model to Mitigate Nonideal Vibrations
(Asme-amer Soc Mechanical Eng, 2009-07-01)
In this paper, a nonideal mechanical system with the LuGre friction damping model is considered. The mechanical model of the system is an oscillator not necessarily linear connected with an unbalanced motor of excitation ...

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 ...
