    • A black-box model for neurons 

      Roqueiro, Nestor; Claumann, Carlos; Guillamon Grabolosa, Antoni; Fossas Colet, Enric (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference lecture
      Open Access
      We explore the identification of neuronal voltage traces by artificial neural networks based on wavelets (Wavenet). More precisely, we apply a modification in the representation of dynamical systems by Wavenet which decreases ...
    • A sliding mode controlled three wheeled narrow vehicle 

      Fossas Colet, Enric; Roqueiro, Nestor; Gaudezi de Faria, Marcelo (2013)
      Article
      Restricted access - publisher's policy
      This paper presents a sliding mode controller for a narrow tilting three-wheeled vehicle. The vehicle is modelled as a dynamic eighteen-order system with two inputs and two outputs, however, a simple third-order model of ...
    • An extension of the unity vector control method 

      Roqueiro, Nestor; Do Carmo, L. M. M.; Silveira, H. B.; Fossas Colet, Enric (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Conference report
      Restricted access - publisher's policy
      In this work, Unity Vector Control is revisited based on the results by V. Utkin and co-workers. The approach here presented extends the one reported by V. Utkin and co-workers so that independent feedback gains may be ...
    • Balanced model order reduction method for systems depending on a parameter 

      Batlle Arnau, Carles; Roqueiro, Nestor (2019)
      Article
      Open Access
      We provide an analytical framework for balanced realization model order reduction of linear control systems which depend on an unknown parameter. Besides recovering known results for the first order corrections, we obtain ...
    • Sliding mode controller and flatness based set-point generator for a three wheeled narrow vehicle 

      Roqueiro, Nestor; de Faria, Marcelo G.; Fossas Colet, Enric (IFAC, 2011)
      Conference report
      Restricted access - publisher's policy
      This paper presents a sliding mode Controller for a narrow tilting three wheeled vehicle. A dynamic model of eighteenth order is presented for simulation purposes only. Design and analysis are based on a simpler third ...
    • Variable-structure control with complementarity-inputs for a lean-burn IC engine of a series hybrid vehicle 

      Roqueiro, Nestor; Fossas Colet, Enric; Martins Oliveira, A. A.; Puleston, Paul Federico (2015-07-01)
      Article
      Open Access
      This paper presents a robust controller for an internal combustion (IC) engine, as the first stage of a project to develop a hybrid light urban vehicle, running on ethanol in lean burn. In particular, this work focuses on ...
