  • An alternative discrete-time model for networked control systems with time delay less than the sampling period 

    Torres Guerrero, Gina; Velasco García, Manel; Martí Colom, Pau; Martín Rull, Enric Xavier; Fuertes Armengol, José Mª (2013)
    Conference lecture
    Restricted access - publisher's policy
    The majority of existing Networked Control Systems (NCS) models are discrete-time formulations based on the exact discretization of the continuous-time linear plant over a sample interval. In the state-space formalism, ...
  • Communication-aware consensus for frequency restoration in islanded microgrids 

    Martí Colom, Pau; Velasco García, Manel; Martín Rull, Enric Xavier; Castilla Fernández, Miguel; Miret Tomàs, Jaume; Camacho Santiago, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Conference report
    Restricted access - publisher's policy
    MicroGrids (MGs) include spatially distributed generation (DG) systems and loads that may require operating autonomously in islanded mode. The operation of islanded MGs can benefit from consensus theory and practice, ...

    The evolution of technology and application needs leads to design complex systems both at hardware and software levels. Modeling approaches and automatic code generation are mature techniques in several application areas ...
  • Lowering traffic without sacrificing performance in networked control systems 

    Martí Colom, Pau; Velasco García, Manel; Yépez Castillo, José Gregorio; Martín Rull, Enric Xavier (IEEE Press. Institute of Electrical and Electronics Engineers, 2011)
    Conference lecture

    A dynamical version of the classical McCulloch & Pitts’ neural model is introduced in this paper. In this new approach, artificial neurons are characterized by: i) inputs in the form of differentiable continuous-time ...
  • Networked sliding mode control of the double integrator system using the event-driven self-triggered approach 

    Martí Colom, Pau; Velasco García, Manel; Camacho Santiago, Antonio; Martín Rull, Enric Xavier; Fuertes Armengol, José Mª (2011)
    Conference lecture
    Restricted access - publisher's policy
    Sliding mode control (SMC) methods rely on applying a high-frequency switching control. In networked control systems (NCS), high-frequency operations/transactions are not desirable because communication bandwidth consumption ...
  • Performance analysis of frequency restoration for parallel voltage source inverters connected with a realistic communication channel 

    Martí Colom, Pau; Velasco García, Manel; Martín Rull, Enric Xavier; Castilla Fernández, Miguel; Miret Tomàs, Jaume; Torres Martínez, Javier (2015)
    Conference lecture
    Restricted access - publisher's policy
    A topic of interest within the microgrid (MG) community is to achieve accurate sharing of active and reactive power among voltage source inverters (VSI) working in parallel while keeping the voltage frequency and amplitude ...
  • Performance evaluation of secondary control policies with respect to digital communications properties in inverter-based islanded microgrids 

    Martí Colom, Pau; Velasco García, Manel; Martín Rull, Enric Xavier; García de Vicuña Muñoz de la Nava, José Luis; Miret Tomàs, Jaume; Castilla Fernández, Miguel (Institute of Electrical and Electronics Engineers (IEEE), 2016-09-12)
    Article
    Open Access
    A key challenge for inverted-based microgrids working in islanded mode is to maintain their own frequency and voltage to a certain reference values while regulating the active and reactive power among distributed generators ...
  • Simulation study of a remote wireless path tracking control with delay estimation for an autonomous guided vehicle 

    Lozoya, Camilo; Martí Colom, Pau; Velasco García, Manel; Fuertes Armengol, José Mª; Martín Rull, Enric Xavier (Springer, 2010-06-01)
