A characterization of hysteresis systems
(2012)
Conference lecture
Restricted access - author's decisionHysteresis is a nonlinear phenomenon exhibited by systems stemming from various science and engineering areas. To detect experimentally the presence of hysteresis in a system, the graph output versus input of the system ... -
A data-driven hysteresis model
(Wiley, 2022-09-12)
Article
Restricted access - publisher's policyHysteresis is a special type of behavior encountered in various fields of science and engineering. In civil engineering and smart structures, the Bouc–Wen model has been used extensively to represent materials with hysteresis. ... -
A new method for the identification of the parameters of the Dahl model
(2016)
Conference report
Open Access -
A survey of the hysteretic Duhem model
(2018-11-01)
Article
Open AccessThe Duhem model is a simulacrum of a com- plex and hazy reality: hysteresis. Introduced by Pierre Duhem to provide a mathematical representation of thermodynamical irreversibility, it is used to ... -
A unified approach for the identification of SISO/MIMO Wiener and Hammerstein systems
(2012)
Conference lecture
Open AccessHammerstein and Wiener models are nonlinear representations of systems composed by the coupling of a static nonlinearity N and a linear system L in the form N-L and L-N respectively. These models can represent real ... -
Adaptive backstepping control of a class of hysteretic systems
(SPIE Press. The International Society for Optical Engineering, 2003-08-01)
Part of book or chapter of book
Open AccessA backstepping-based adaptive control is designed for a class of one degree of freedom hysteretic system. The true hysteretic behavior does not need to be known for the controller design. A polynomial description is assumed ... -
Adaptive backstepping control of some uncertain nonlinear oscillators
(IEEE Press. Institute of Electrical and Electronics Engineers, 2003-12)
Part of book or chapter of book
Open AccessA backstepping-based adaptive controller is designed for a class of uncertain second orded nonlinear systems under the strict-feedback form. It is shown that the closed loop is globally uniformly ultimately bounded and we ... -

An asymmetric-friction based model for magnetorheological dampers
(2017)
Conference report
Open AccessThe modeling of magnetorheological dampers combines the use of the laws of physics along with a phenomenological description. The phenomenological models that are used to describe these devices present a symmetric ... -
Bounded and dissipative solutions of the Bouc-Wen model for hysteretic structural systems
(2004-06)
Part of book or chapter of book
Open AccessThe aim of this paper is to give the conditions on the hysteretic Bouc-Wen model so that (i) it has the property of being bounded input bounded output (BIBO), and (ii) it dissipates energy (or is passive). This study leads ... -
Causal canonical decomposition of hysteresis systems
(2020-10-01)
Article
Open AccessHysteresis is a special type of behavior found in many areas including magnetism, mechanics, bi-ology, economics, etc. One of the characteristics of hysteresis systems is that they are approximatelyrate independent for ... -
Characterization of a class of differential equations
(2017-01-01)
Article
Open AccessThis paper deals with a characterization of nonlinear systems of the form x<sub>¿</sub> (t) = f (x<sub>¿</sub>(t), u(t/¿)) when the parameter ¿ ¿ 8. In particular, we are interested in the uniform convergence of the sequence ... -
Characterization of the hysteresis Duhem model
(2014)
Conference lecture
Open AccessThe Duhem model, widely used in structural, electrical and mechanical engineering, gives an analytical description of a smooth hysteretic behavior. In practice, the Duhem model is mostly used within the following black-box ... -

Article
Open AccessAquest article presenta el desenvolupament i primers resultats d'ús d'un conjunt de cursos virtuals que pretenen proporcionar uns coneixements inicials bàsics de Matemàtiques, Física i !ímica als estudiants que accedeixen ... -
Frequency identification of Wiener systems with Backlash operators using separable least squares estimators
(2012)
Conference lecture
Open AccessThis paper deals with the identification of Wiener models that involve backlash operators bordered by possibly noninvertible parametric lines. The latter are also allowed to cross each other making possible to account for ... -
H8 control design for mechanisms with backlash
(2009)
Conference lecture
Restricted access - publisher's policyAn H∞ output feedback control design is presented for mechanisms with backlash, under the presence of external perturbation. Using the static dead-zone model as a simpler model for backlash, the non-linear problem is cast ... -
Hysteresis loop of the LuGre model
(2015-09-01)
Article
Open AccessThe LuGre friction model is used in the current literature to describe the friction phenomenon for mechanical systems. In this paper, we focus on the hysteresis behaviour of the model. More precisely, we describe analytically ... -
Identification of a system with dry friction
(2005-09)
Research report
Open AccessA new elasto-plastic state variable friction model is proposed which models both stiction and presliding displacement. However, the proposed Leuven model by Swevers et al. is more complex than the standard parameterization ... -

Minor loops of the Dahl and LuGre models
(2020-01)
Article
Open AccessHysteresis is a special type of behavior encountered in physical systems: in a hysteretic system, when the input is periodic and varies slowly, the steady-state part of the output- versus-input graph becomes a loop called ...
