    • Investigation of a method for predicting AUV derivatives 

      Barros, E.A. de; Pascoal, A.; Desa, E.S. (Elsevier, 2008)
      The paper addresses the problem of autonomous underwater vehicle (AUV) modelling and parameter estimation as a means to predict the dynamic performance of underwater vehicles and thus provide solid guidelines during their ...
    • Magnetic navigation and tracking of underwater vehicles 

      Teixeira, F.C.; Pascoal, A.M. (International Federation of Automatic Control, 2013)
      This paper proposes novel methods with the potential to improve the performance of navigation and tracking systems in underwater environments. The work relies on well-established methods of potential field inversion and ...
    • Marine vehicle path following using inner-outer loop control. 

      Maurya, P.; Agular, A.P.; Pascoal, A.M. (IFAC International Conference, 2009)
      This paper addresses the problem of marine vehicle path following using innerouter loop control, with due account for the vehicle dynamics. We propose an inner-outer control structure that lends itself to a simple intuitive ...
    • Observability analysis of 2D single-beacon navigation in the presence of constant currents for two classes of maneuvers 

      Crasta, N.; Bayat, M.; Aguiar, A.P.; Pascoal, A.M. (International Federation of Automatic Control, 2013)
      We analyze the observability properties of an underwater vehicle (moving in 2D) performing single beacon navigation for two specic classes of maneuvers, whereby the vehicle measures its distance to a xed transponder located ...
    • Optimal Sensor placement for acoustic range-based underwater robotic positioning 

      Glotzbach, T.; Moreno-Salinas, D.; Aranda, J.; Pascoal, A.M. (International Federation of Automatic Control, 2013)
      This paper addresses the problem of optimal sensor placement for acoustic range-based underwater target positioning. In particular, we focus on the experimental set-up whereby target positioning is ...
