Model of an artificial neural network for optimization of payload positioning in sea waves

The optimization problem considered is to define the rotation function of a winch which compensates vibrations of the crane placed on a vessel deck. The aim is to stabilize the payload at a given depth or realize a predefined trajectory despite the sea waves and vessel motion. The model of the flexible rope formulated by means of the rigid finite element method allows us to,consider both hydrodynamic forces when a part of the rope is submerged and the complex shape of the rope due to its large displacements. An artificial neural network is proposed to control the position of the payload. (C) 2016 Elsevier Ltd. All rights reserved.
