Adaptive backstepping control of a class of hysteretic systems
Ikhouane, Fayçal; Mañosa Fernández, Víctor; Rodellar Benedé, José (SPIE Press. The International Society for Optical Engineering, 20030801)
Part of book or chapter of book
Open AccessA backsteppingbased 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
Ikhouane, Fayçal; Mañosa Fernández, Víctor; Rodellar Benedé, José (IEEE Press. Institute of Electrical and Electronics Engineers, 200312)
Part of book or chapter of book
Open AccessA backsteppingbased adaptive controller is designed for a class of uncertain second orded nonlinear systems under the strictfeedback form. It is shown that the closed loop is globally uniformly ultimately bounded and we ... 
An analyticnumerical method of computation of the Liapunov and period constants derived from their algebraic structure
Gasull Embid, Armengol; Guillamon Grabolosa, Antoni; Mañosa Fernández, Víctor (1996)
Article
Open AccessWe consider the problem of computing the Liapunov and the period constants for a smooth differential equation with a non degenerate critical point. First, we investigate the structure of both constants when they are ... 
An explicit expression of the first Liapunov and period constants with applications
Gasull Embid, Armengol; Guillamon Grabolosa, Antoni; Mañosa Fernández, Víctor (1996)
Article
Open AccessIn this paper, we study systems in the plane having a critical point with pure imaginary eigenvalues, and we search for effective conditions to discern whether this critical point is a focus or a center; in the case of it ...

A route to chaos in the BorosMoll map
Gardini, Laura; Mañosa Fernández, Víctor; Sushko, Iryna (20180418)
External research report
Open AccessThe BorosMoll map appears as a subsystem of a Landen transformation associated to certain rational integrals and its dynamics is related to the convergence of them. In the paper, we study the dynamics of a oneparameter ...

Basin of attraction of triangular maps with applications
Cima Mollet, Anna; Gasull Embid, Armengol; Mañosa Fernández, Víctor (20130725)
External research report
Open AccessWe consider some planar triangular maps. These maps preserve certain fibration of the plane. We assume that there exists an invariant attracting fiber and we study the limit dynamics of those points in the basin of attraction ...

Bifurcation of 2periodic orbits from nonhyperbolic fixed points
Cima Mollet, Anna; Gasull Embid, Armengol; Mañosa Fernández, Víctor (20170721)
External research report
Open AccessWe introduce the concept of 2cyclicity for families of onedimensional maps with a nonhyperbolic fixed point by analogy to the cyclicity for families of planar vector fields with a weak focus. This new concept is useful ...

Bounded and dissipative solutions of the BoucWen model for hysteretic structural systems
Ikhouane, Fayçal; Mañosa Fernández, Víctor; Rodellar Benedé, José (200406)
Part of book or chapter of book
Open AccessThe aim of this paper is to give the conditions on the hysteretic BoucWen 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 ... 
Centre and isochronicity conditions for systems with homogeneous nonlinearities
Gasull Embid, Armengol; Guillamon Grabolosa, Antoni; Mañosa Fernández, Víctor (1995)
Article
Open AccessWe study the centrefocus problem for systems with homogeneous nonlinearities. In the centre case we study the characterization of the isochronous centres. More explicitly, we derive six necessary conditions to be a ... 
Continua of periodic points for planar integrable rational maps
Gasull Embid, Armengol; Llorens, Mireia; Mañosa Fernández, Víctor (Research India Publications, 201609)
Article
Open AccessWe present three alternative methodologies to find continua of periodic points with a prescribed period for rational maps having rational first integrals. The first two have been already used by other authors and apply ...
