Identification of longitudinal and transversal dynamics of a fast ferry
An analysis of the system identification methods have been carried out and a new alternative approach is proposed in order to estimate models for heave, pitch and roll dynamics of a high speed craft. As starting point, a first approach resolves the identification subject as an optimization problem to fit the best model, and uses genetic algorithms and nonlinear least squares with constraints me...
متن کاملNeuro-fuzzy System to Control the Fast Ferry Vertical Acceleration
This paper shows the design of a neuro-fuzzy system to control the vertical motion of a TF-120 fast ferry, so that to improve the passengers comfort by reducing the main cause of seasickness. The aim of this controller is to decrease the pitch acceleration by controlling the position of some actuators, varying their working angles. The controller is based on a fuzzy model of the ship behaviour....
متن کاملNeuro-fuzzy Modelling of a Fast Ferry Vertical Motion
A neuro-fuzzy system has been developed to model the behaviour of a fast ferry. The sources of the available knowledge are the physical laws of the vertical dynamics of the craft, and some experimental and simulated data of the ship performance in regular waves. The non-linear model has been obtained by applying adaptive neurofuzzy inference. It is focus on the vertical motion of the craft, bot...
متن کاملQft versus Classical Gain Scheduling: Study for a Fast Ferry
In this paper a comparative study of two different control strategies is done: Gain scheduling with classic controllers (PD and second order filter) versus QFT. Both of them are used to decrease motion sickness in a high speed ferry produced by the vertical acceleration associated with heave and pitch motion. Copyright 2002 IFAC
متن کاملA ferry between cultures
the new field of research into the ethical, legal and social aspects of scientific and technological developments (ElSa) is rapidly becoming a professional field with grants, research programmes and university departments devoted to it. at first glance, ElSa seems to be a new development intended to address questions and challenges that arise from advances in the natural sciences. the professio...
