A feedback-based L-2-norm limiter for periodic signals
(2011-01)
Article
Restricted access - publisher's policyLimiting the rms value (L2 norm) of periodic signals can be a necessity in some controllers for power electronic devices. The prevailing existing solution is simply to compute, off-line, the L2 norm and then to multiply ... -
A flexoelectric microelectromechanical system on silicon
(2016)
Article
Open AccessFlexoelectricity allows a dielectric material to polarize in response to a mechanical bending moment and, conversely, to bend in response to an electric field. Compared with piezoelectricity, flexoelectricity is a weak ... -
A high order finite element formulation for the simulation of 3D Magneto-Mechanical problems with application to MRI scanners
(2019)
Conference report
Restricted access - publisher's policyTransient magnetic fields generated by the gradient coils in MRI scanners induce eddy currents in their conducting components, which lead to vibrations, imaging artefacts, noise and the dissipation of heat. Heat dissipation ... -
A jerk threshold-based involuntary lateral movement algorithm
(2009)
Conference lecture
Open AccessAlgorithms for automatic fall detection are often studied in the field of ambulatory human health supervision. These algorithms are developed to generate hospital emergency alarms. In the present paper, Involuntary ... -
A method for fault detection and diagnostics in ventilation units using virtual sensors
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-11-14)
Article
Open AccessBuildings represent a significant portion of global energy consumption. Ventilation units are complex components, often customized for the specific building, responsible for a large part of energy consumption. Their faults ... -
A multidimensional data-driven sparse identification technique: the sparse proper generalized decomposition
(2018-01-01)
Article
Open AccessSparse model identification by means of data is especially cumbersome if the sought dynamics live in a high dimensional space. This usually involves the need for large amount of data, unfeasible in such a high dimensional ... -
A novel framework to assess the wake vortex hazards risk supported by aircraft in en-route operations
(2017)
Conference report
Open AccessThis paper presents the simulation environment developed within the framework of R-WAKE project, funded by SESAR 2020 Exploratory Research. This project aims to investigate the risks and hazards of potential wake ... -
A Passivity-based controller without velocity measurements for the leaderless consensus of Euler-Lagrange systems
(2017-07-01)
Article
Open AccessThis paper deals with the problem of achieving consensus of multiple interconnected Euler-Lagrange (EL) systems using the energy shaping plus damping injection principles of passivity-based control. It proposes a novel ... -
A practical approach to HFI based sensorless control of PM-assisted synchronous reluctance machines applied to EVs and HEVs
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Conference report
Restricted access - publisher's policySensorless control is a promising alternative for controlling Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) propulsion systems without the need of complex devices, such as resolvers or encoders. As the usage of ... -
A proportional resonant controller tuning method for grid connected power converters with LCL+trap filter
(2014)
Conference report
Restricted access - publisher's policyThree-phase power converters are largely employed in power generation facilities based on renewable energy sources, and these converters commonly working in grid connection mode are frequently connected to the grid through ... -
A robust LMI approach on nonlinear feedback stabilization of continuous state-delay systems with Lipschitzian nonlinearities : experimental validation
(2019-09)
Article
Open AccessThis paper suggests a novel nonlinear state-fe edback stabilization control law using linear matrix inequalities for a class oftime-delayed nonlinear dynamic systems with Lipschitz nonlinearity conditions. Based on the ... -
A stator voltage oriented PI controller for the doubly-fed induction machine
(Institute of Electrical and Electronics Engineers, 2007)
Conference report
Open AccessIn this paper we propose a new control scheme for the doubly–fed induction machine (DFIM) that offers significant advantages, and is considerably simpler, than the classical vector control method. In contrast with the ... -
A structural encoding technique for the synthesis of asynchronous circuits
(Institute of Electrical and Electronics Engineers (IEEE), 2001)
Conference report
Open AccessThis paper presents a method for the automatic synthesis of asynchronous circuits from Petri net specifications. The method is based on a structural encoding of the system in such a way that a circuit implementation is ... -
A supervisory control scheme for uncertain constrained time-delay discrete-time linear systems
(2023-09-01)
Article
Restricted access - publisher's policyIn this paper, a two-layer supervisory control scheme is proposed for discrete-time linear systems with state/input constraints, including multiple state time-delays, parametric uncertainties, and exogenous disturbance. ... -

A two-tank benchmark for detection and isolation of cyber attacks
(2018-01-01)
Article
Open AccessThis paper presents a benchmark for the detection and isolation of cyber attacks, which is a non-linear controlled interconnected system based on a two tank system. In this benchmark, a malicious attacker wants to remain ... -
A zonotopic-based watermarking design to detect replay attacks
(2022-11)
Article
Open AccessThis paper suggests the use of zonotopes for the design of watermark signals. The proposed approach exploits the recent analogy found between stochastic and zonotopic-based estimators to propose a deterministic counterpart ... -
Abnormal quality detection and isolation in water distribution networks using simulation models
(2012-11-16)
Article
Open AccessThis paper proposes a model based detection and localisation method to deal with abnormal quality levels based on the chlorine measurements and chlorine sensitivity analysis in a water distribution network. A fault isolation ... -
