Ship roll damping control
The technical feasibility of roll motion control devices has been amply demonstrated for over 100 years. Performance, however, can still fall short of expectations because of difficulties associated with control system designs, which have proven to be far from trivial due to fundamental performance limitations and large variations of the spectral characteristics of wave-induced roll motion. Thi...
متن کاملAdaptive Direct Inverse Neural Network Control for Nonlinear System
In this paper is proposed an on-line method for Direct Inverse Control (DIC) based on Neural Network (NN) for nonlinear system. The corresponding algorithm uses a variable learning rate. The proposed method is dependent on the availability of the inverse model of the system. This obtained on-line inverse model will be used as a controller. This latter is used in series with the process. The rob...
متن کاملShip Roll Motion Control
The technical feasibility of roll motion control devices has been amply demonstrated for over 100 years. Performance, however, can still fall short of expectations because of deficiencies in control system designs, which have proven to be far from trivial due to fundamental performance limitations. This tutorial paper presents an account of the development of various ship roll motion control sy...
متن کاملStochastic Inverse Identification of Nonlinear Roll Damping Moment of a Ship Moving at Nonzero-Forward Speeds
The nonlinear responses of ship rolling motion characterized by a roll damping moment are of great interest to naval architects and ocean engineers. Modeling and identification of the nonlinear damping moment are essential to incorporate the inherent nonlinearity in design, analysis, and control of a ship. A stochastic nonparametric approach for identification of nonlinear damping in the genera...
متن کاملThe Problems with Direct Inverse Neural Control
The paper deals with the analysis and synthesis of the nonlinear plant by means of the direct inverse neural control. The direct inverse control is one of the simplest control methods at all. But it has some disadvantages which will be briefly discussed: the rate of the input signal is very reduced, problems arise if the mathematical plant description is not known and customary used backpropaga...
