EXPERIMENTAL OBSERVATION OF NONLINEAR VIBRATIONS USING A CLOSED-LOOP VIBRATION SYSTEM
(Polish Acad Sciences, 2015-12-01)
This paper presents experimental observation of nonlinear vibrations in the response of a flexible cantilever beam to transverse harmonic base excitations around its flexural mode frequencies. In the experimental setup, ...
State estimation in batch processes using a nonlinear observer
(Pergamon-Elsevier Science Ltd, 2006-12)
This paper deals with the problem of nonlinear states estimation in batch chemical processes. It presents a reduced-order nonlinear observer approach to perform the estimation. The proposed method allows adjustment of the ...
Nonlinear optical absorption of antimony and lead oxyhalide glasses
(2003-12-16)
The optical limiting behavior and nonlinear optical properties of antimony and lead oxyhalide glasses were discussed. The large nonlinear absorption coefficients which range from 11 to 20 cm/GW was determined using standard ...

On the response at the excitation frequency of a two degrees of freedom nonlinear oscillator
(2017-01-01)
This paper presents an overview of the main theoretical advances and experimental analyses, achieved by the authors in recent years of collaborative research in the field of nonlinear dynamics of coupled oscillators. The ...
Fast nonlinear region localisation for nonlinear dielectric spectroscopy of biological suspensions
(Elsevier Science, 2013-06)
The nonlinear properties of biological suspensions have been previously presented as a bulk phenomenon without the influences of the electrodes. However, some authors have showed that the behaviour of a biological suspension ...
Updating of a nonlinear finite element model using discrete-time volterra series
(2017-01-01)
In this study, the discrete-time Volterra series are used to update parameters in a nonlinear finite element model. The main idea of the Volterra series is to describe the discrete-time output of a nonlinear system using ...
Nonlinear dynamical analysis of an aeroelastic system with multi-segmented moment in the pitch degree-of-freedom
(Elsevier B.V., 2015-01-01)
The effects of a multi-segmented nonlinearity in the pitch degree of freedom on the behavior of a two-degree of freedom aeroelastic system are investigated. The aeroelastic system is free to plunge and pitch and is supported ...
Design of reduced-order nonlinear observers for energy conversion applications
(Institution of Engineering and Technology, 2010-05)
Here a systematic technique to design a reduced-order nonlinear observer for estimating signals in application to energy conversion systems is introduced. This observer presents a linear error dynamics in estimated variables ...
