Control design applied to a non-ideal structural system with behavior chaotic
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
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 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 ...
On an Optimal Linear Control of a Chaotic Non-Ideal Duffing 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 ...
Quenching in a non-ideal mechanical system and the Averaging Method
In this paper, for the first time, a quenching result in a non-ideal system is rigorously obtained. In order to do this a new mechanical hypothesis is assumed, it means that the moment of inertia of the rotating parts of ...
A Short Note on a Nonlinear System vibrations under Two Non-Ideal Excitations
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 ...
Chaos control via state-dependent riccati equation method applied a non-ideal vibration absorber coupled to a nonlinear oscillator
The non-ideal vibration absorber system coupled to a nonlinear oscillator is proposed in the paper. This system is demonstrated with a chaotic behavior and we present the control technical for the chaos stabilization. The ...
