Photovoltaic inverters with fault ride-through capability
(ISIE, 2009)
Conference lecture
Open AccessThis paper presents a new control strategy that allow the photovoltaic system operate under grid faults without overpass the rated current and assuring sinusoidal currents. In the classic control strategies used in ... -
Symmetrical and unsymmetrical voltage sag effects on the three-phase synchronous machine stability
(2009)
Conference lecture
Open AccessThis paper focuses on the effects of voltage sags, both symmetrical and unsymmetrical, on the three-phase Synchronous Machine (SM). Voltage sags on SM cause speed variations, current and torque peaks and hence may cause ... -
Distributed cooperative control for stepper motors synchronization
(2018)
Conference report
Open AccessThis paper describes the design and simulation of a distributed cooperative control algorithm based on multi-agents to synchronize a group of stepper motors. Modeling of the two-phase hybrid stepper motor in closed loop ... -
Observer design for Takagi-Sugeno Lipschitz systems affected by disturbances using quadratic boundedness
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessIn this paper, a proportional observer design using quadratic boundedness is proposed in order to estimate the state of a system described by a Takagi-Sugeno model with a Lipschitz nonlinearity term, and affected by unknown ... -
Economic MPC-LPV control for the operational management of water distribution networks
(Elsevier, 2019)
Conference report
Open AccessThis paper presents an Economic Model Predictive Control (EMPC) for the operational management of water distribution networks (WDNs) with periodic operation based on embedding the nonlinearity of the model to the Linear ... -
Set-based replay attack detection in closed-loop systems using a plug & play watermarking approach
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessThis paper presents a watermarking signal injection method that compensates its effect in the loop, avoiding thus the signal reinjection. Similar to a virtual actuator scheme, the proposed methodology masks the presence ... -
LPV-MPC control of autonomous vehicles
(2019)
Conference report
Open AccessIn this work, a novel approach is presented to solve the trajectory tracking problem for autonomous vehicles. This method is based on the use of a cascade control where the external loop solves the position control using ... -
Nonlinear observer design for PEM fuel-cell systems using first-order sliding mode techniques
(2017)
Conference report
Open AccessThis paper presents a nonlinear observer design for Proton Exchange Membrane Fuel-Cell (PEMFC) systems. The aim of the proposed observer is to reconstruct the oxygen excess ratio through the estimation of their relevant ... -
Modelling liquid water effect on proton-exchange membrane fuel cells
(2019)
Conference report
Open AccessThis work introduces our ongoing research in developing accurate models for predicting and analyzing Proton-Exchange Membrane Fuel Cells performance. An initial model, whose response is compared with experimental data is ... -
Frequency-based detection of replay attacks: application to a quadrotor UAV
(2019)
Conference report
Open AccessUnmanned aerial vehicles (UAVs) are reported to be highly exposed as possible targets of cyber attacks, due to their strong strategic and economic value, and their increasing use in a wide range of operations. Among the ... -
Modelling of solid oxide electrolizer and hydrogen leak estimation
(2019)
Conference report
Open AccessSolid Oxide Elecyrolizers (SOEC) are electrochemical devises that produce hydrogen from water using the energy of an electric power source. SOEC operate at high temperatures (around 800ºC) and have efficiencies around 53% ... -
State observer design for quadratic parameter varying (QPV) systems
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessThis paper addresses the problem of state observation in quadratic parameter varying (QPV) systems. In particular, a state observer is designed in such a way that the estimation error converges to zero with a desired rate ...
