Master thesis (pre-Bologna period)
Open Access[ANGLÈS] This work is focused on DC to DC conversion, what is a crucial function to enable the use of supercapacitors for energy storage. A theoretical study and comparison of methods, algorithms and techniques for software ...
Restricted access - publisher's policyThis paper presents the design of a sliding mode control strategy through an input decoupling of an hybrid fuel cell based system. The hybrid system is composed by a fuel cell stack and a Supercapacitors module, connected ...
Restricted access - publisher's policyIn this paper different cascaded and multilevel topologies are compared for regenerative braking systems using supercapacitors (SC). It shows that the multilevel buck derived topology can beneficiate from both reduced ...
(IEEE Computer Society Publications, 2011)
Restricted access - publisher's policyThe level of penetration of grid-connected photovoltaic (PV) systems has grown very quickly in recent years. Nonetheless, network stresses related to the recurrent voltage and frequency oscillations caused by their irregular ...

Restricted access - publisher's policyIn control theory, sliding mode control, or SMC, is a nonlinear control method that alters the dynamics of a nonlinear system by application of a discontinuous control signal that forces the system to "slide" along a ...
Sliding-mode control for a three-phase unity power factor rectifier operating at fixed switching frequency (2015-02-11)
Open AccessThis paper presents an improved variable hysteresisband current-control in natural frame for a three-phase unity power rectifier. The proposed control algorithm is based on three decoupled sliding-mode controllers combined ...
Two Families of Sliding Mode Controllers for a Doubly-Fed Induction Generator in a Isolated Generation System (Institute of Electrical and Electronics Engineers (IEEE), 2007-05)
Open AccessEn este artículo se considera el control en modo de deslizamiento (SMC1) de un generador de inducción doblemente alimentado (DFIG) que suministra a una carga RL aislada, en un sistema de generación de velocidadvariable/f ...
