Minor loops of the Dahl and LuGre models

Ikhouane, Fayçal; Mañosa Fernández, Víctor; Pujol Vázquez, Gisela (2020-01)
Article
Accés obert

Hysteresis 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 ...

Magnetorheological (MR) dampers are promising vibration control devices widely used for vibration mitigation applications as they combine reliability and stability of passive systems while maintaining versatility of active ...

On babuška's model for asymmetric hysteresis

Ikhouane, Fayçal (2021-04-01)
Article
Accés obert

Hysteresis is a complex phenomenon that occurs in many areas of science and engineering. To model hysteresis, scientists combine first laws of physics with fictitious equations to obtain phenomenological models that aim ...

Stability of time-varying systems in the absence of strict Lyapunov functions

Naser, Mohammad Fuad Mohammad; Ikhouane, Fayçal (2019-06-01)
Article
Accés obert

When a non-linear system has a strict Lyapunov function, its stability can be studied using standard tools from Lyapunov stability theory. What happens when the strict condition fails? This paper provides an answer to that ...

System identification of a class of Wiener systems with hysteretic nonlinearities

radouane, Abdelhadi; Giri, Fouad; Ikhouane, Fayçal; Ahmed-Ali, Tarek; Chaoui, Fatima Zahra; Brouri, Adil (2017-03-01)
Article
Accés obert

Existing works on Wiener system identification have essentially been focused on the case where the output nonlinearity is memoryless. When memory nonlinearities have been considered, the focus has been restricted to backlash ...
