On the Chaotic Suppression of Both Ideal and Non-ideal Duffing Based Vibrating Systems, Using a Magnetorheological Damper
(2013-01-10)
In this paper the dynamics of the ideal and non-ideal Duffing oscillator with chaotic behavior is considered. In order to suppress the chaotic behavior and to control the system, a control signal is introduced in the system ...
An Optimal Linear Control Design for Nonlinear Systems
(Abcm Brazilian Soc Mechanical Sciences & Engineering, 2008-10-01)
This paper studies the linear feedback control strategies for nonlinear systems. Asymptotic stability of the closed-loop nonlinear system is guaranteed by means of a Lyapunov function, which can clearly be seen to be the ...
Comments on nonlinear dynamics of a non-ideal Duffing-Rayleigh oscillator: Numerical and analytical approaches
(Academic Press Ltd Elsevier B.V. Ltd, 2009-01-23)
An analytical and numerical investigation into the dynamic interaction between a cantilever beam with nonlinear damping and stiffness behavior, modeled by the Duffing-Rayleigh equation, and a non-ideal motor that is connected ...
On the performance of a dual-mode non-linear vibration energy harvesting device
(Sage Publications Ltd, 2012-09-01)
The research trend for harvesting energy from the ambient vibration sources has moved from using a linear resonant generator to a non-linear generator in order to improve on the performance of a linear generator; for ...
Bifurcation Analysis of a Van der Pol-Duffing Circuit with Parallel Resistor
(Hindawi Publishing Corporation, 2009-01-01)
We study the local codimension one, two, and three bifurcations which occur in a recently proposed Van der Pol-Duffing circuit (ADVP) with parallel resistor, which is an extension of the classical Chua's circuit with cubic ...
Basins of attraction changes by amplitude constraining of oscillators with limited power supply
(Elsevier B.V., 2005-11-01)
We investigate the dynamics of a Duffing oscillator driven by a limited power supply, such that the source of forcing is considered to be another oscillator, coupled to the first one. The resulting dynamics come from the ...
A non-ideal portal frame energy harvester controlled using a pendulum
(2013-09-01)
A model of energy harvester based on a simple portal frame structure is presented. The system is considered to be non-ideal system (NIS) due to interaction with the energy source, a DC motor with limited power supply and ...
Identification of nonlinear structures using discrete-time Volterra series
