    An analysisof models identification methods for high speed crafts
    (Journal of Maritime Research, 2005-01-01) Dormido Bencomo, Sebastián; Aranda Almansa, Joaquín; Muñoz Mansilla, María del Rocío; Dormido Canto, Sebastián; Díaz Martínez, José Manuel
    Two different approaches of the system identification method have been proposed in order to estimate models for heave, pitch and roll dynamics of a high speed craft. Both of them resolve the identification subject as an optimization problem to fit the best model. The first approach uses genetic algorithms and nonlinear least squares with constraints methods applied in the frequency domain. The second one suggests a new parameterization which facilitates obtaining high quality starting values and avoids non-quadratic functions in the cost function. At last it is shown an example in which the two approximations are applied and compared.

    Interactive computer-aided control design using quantitative feedback theory: the problem of vertical movement stabilization on a high-speed ferry
    (Taylor and Francis, 2005-07-20) Dormido Bencomo, Sebastián; Díaz Martínez, José Manuel; Aranda Almansa, Joaquín
    In a first approximation, the vertical acceleration associated with pitch motion can be considered as the main cause of motion sickness, which is without a doubt one of the most unpleasant disadvantages of maritime transport. The reduction of motion sickness can be stated as a monovariable regulation problem of a highly perturbed system. This work presents the design of a monovariable robust controller with quantitative feedback theory (QFT) for reducing the vertical movement on a high-speed ferry. The different stages of QFT methodology have been done with the help of the software tool QFTIT (Quantitative Feedback Theory Interactive Tool). This is a free software tool that is characterized by its ease of use and interactive nature. The designed regulator is validated experimentally in sea behaviour trials with a scaled down replica 1/25 the size of a high-speed ferry. The designed regulator is also compared with a gain-scheduling scheme using a proportional and derivative controller (PD).
