  • A mixed-signal architecture for high complexity CMOS fuzzy controllers 

    Navas González, Rafael; Vidal Verdú, Fernando; Rodríguez-Vázquez, Ángel (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
    Article
    Open Access
    Analog circuits provide better area/power efficiency than their digital counterparts for low-medium precision requirements [1]. This limit in precision, as well as the lack of design tools when compared to the digital ...
  • Automatic regulation of wastewater discharge 

    Bolea Monte, Yolanda; Grau Saldes, Antoni (EDP Sciences, 2017)
    Conference report
    Open Access
    Wastewater plants, mainly with secondary treatments, discharge polluted water to environment that cannot be used in any human activity. When those dumps are in the sea it is expected that most of the biological pollutants ...
  • Disseny d'un sistema de control per a la generació d'electricitat basat en energia solar 

    Grébol Nogueras, Oriol (Universitat Politècnica de Catalunya, 2013-06)
    Master thesis (pre-Bologna period)
    Open Access
    En aquest projecte es dissenyarà un sistema de generació d'electricitat a partir d'una placa solar fotovoltaica. El sistema d'energia renovable consisteix en un panell solar, un convertidor de tensió i una bateria per poder ...
  • Event-driven optimization-based control of hybrid systems with integral continuous-time dynamics 

    Di Cairano, S.; Bemporad, A; Julvez Bueno, Jorge Emilio (2009-05)
    Article
    Restricted access - publisher's policy
    In this paper we introduce a class of continuous-time hybrid dynamical systems called integral continuous-time hybrid automata (icHA) for which we propose an event-driven optimization-based control strategy. Events include ...
  • Fuzzy expert system for the detection of episodes of poor water quality through continuous measurement 

    Angulo Bahón, Cecilio; Cabestany Moncusí, Joan; Rodríguez, Pablo; Batlle, Montserrat; González, Antonio; de Campos, Sergio (2012)
    Article
    Open Access
    In order to prevent and reduce water pollution, promote a sustainable use, protect the environment and enhance the status of aquatic ecosystems, this article deals with the application of advanced mathematical techniques ...
  • Helicopter mathematical modelling and optimal controller design 

    Ifkirne, Said (Universitat Politècnica de Catalunya, 2015-11-17)
    Bachelor thesis
    Open Access
    In this bachelor thesis, a nonlinear mathematical model simulation and linear controller design for the U1-H1 helicopter was achieved. This thesis is divided into two parts. In the first part, the nonlinear dynamic model ...
  • Invariant manifolds as boundaries for event-driven control systems 

    Velasco García, Manel; Martí Colom, Pau (2010)
    Conference lecture
    Open Access
    In event-driven control approaches, control updates are triggered by event conditions that are often characterized by different types of boundaries defined in the state-space domain. In this paper we define an event-driven ...
  • Leak Detection and Isolation in Pressurized Water Pipe Networks using Interval LPV Models 

    Vento Maldonado, Jorge; Puig Cayuela, Vicenç (2009-11-19)
    Conference report
    Open Access
  • Leak Detection, Isolation and Estimation in Pressurized Water Pipe Networks using LPV Models and Zonotopes 

    Blesa Izquierdo, Joaquim; Puig Cayuela, Vicenç; Saludes Closa, Jordi; Vento Maldonado, Jorge (2010)
    Conference report
    Open Access
    In this paper, a leak detection, isolation and estimation methodology in pressurized water pipe networks is proposed. The methodology is based on computing residuals which are obtained comparing measured pressures (heads) ...
  • Nonlinear predictive control for the four-tanks plant flow regulation 

    Luna Pacho, Julio Alberto; Acevedo Valle, Juan M.; Rosanas Boeta, Noe; Costa Castelló, Ramon (2014)
    Conference report
    Restricted access - publisher's policy
    The four-tanks system is well-known and a considerable number of works study it in the existent literature. This work proposes a nonlinear model predictive control (NMPC) design to regulate the water ¿ow inputs of the four ...
