SAC - Sistemes Avançats de Control
El grup SAC és un grup de recerca de la UPC actiu des del 1990 i l'any 2014 va ser reconegut com a grup de recerca consolidat. Des del seu inici, l'activitat científica del grup gira a l'entorn de temes relacionats amb la Supervisió, Seguretat i el Control Automàtic de sistemes i infraestructures crítiques.
Actualment, l'activitat científica del grup està organitzada a l'entorn dels següents temes:
- Mineria, validació correcció i fusió de dades heterogènies al el suport de informació cognitiva;
- Disseny de sistemes de diagnosis i control tolerants a fallades, resilients i segurs;
- Prognosis per estimar la salut dels sistemes i desenvolupar metodologies de manteniment predictiu.
- Disseny de sistemes de control òptim i gestió optimitzada de la producció
- Planificació de trajectòries i guiatge de vehicles autònoms.
Dins d'aquests àmbits el grup SAC està reconegut internacionalment fet que ho demostra el gran nombre de col·laboracions internacionals que té.
The group aim is to carry out applied research in the following areas: - Modelling, identification and simulation of continuous and discontinuous industrial processes
- Advanced control of dynamic systems
- Optimisation and constraint satisfaction
- Supervision and fault diagnosis of industrial processes and systems
- Fault-tolerant control; and related subjects.
The aim is to devise software applications that increase the reliability and performance of processes and systems on the basis of this research.

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 ... -

(2009-03)
Article
Open AccessImprovements in torque at low currents using a rotor with spiral sheets are analyzed. Several rotors and stators have been built combining different constructive and mechanical characteristics of the related elements: ... -
Reduced-order models of squirrel-cage induction generators for fixed-speed wind turbines under unbalanced grid conditions
(2016-06)
Article
Open AccessThis paper develops a study of reduced-order models for squirrel-cage induction generators used in the fixed-speed wind turbines. The squirrel-cage of these generators must be modeled with a double-cage for accuracy purposes. ... -
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 ... -
Integration of cold ironing and renewable sources in the Barcelona smart port
(2019-11)
Article
Restricted access - publisher's policyCold ironing, which is the procedure of supplying shoreside electrical power to a ship at berth when its engines are turned off, arises as the eco-friendly way to deliver power to ships while they are berthed in ports, ... -
A survey and evaluation of the potentials of distributed ledger technology for peer-to-peer transactive energy exchanges in local energy markets
(2019-09)
Article
Restricted access - publisher's policyTheunpredictability and intermittency introduced by Renewable Energy Sources (RESs) in power systems may lead to unforeseen peaks of energy production, which might differ from energy demand. To manage these mismatches, a ... -
Doubly fed induction generator-based variable-speed wind turbine: proposal of a simplified model under a faulty grid with short-duration faults
(2019-08)
Article
Open AccessThe aim of this study is to provide a simplified model of a variable-speed wind turbine (VSWT) with the technology of a doubly-fed induction generator (DFIG) which operates under faulty grid conditions. A simplified model ... -
