This paper presents the procedure for designing a Dynamic Positioning system and evaluating its performance using a dynamic approach. Generally, static analysis is the standard preliminary design method for a Dynamic Position system; however, this has some drawbacks for a realistic representation of the system operating in real conditions since...

This paper aims to present a novel approach to design a dynamic positioning system by using a dynamic model based-design approach. The proposed study has been performed to both develop and preliminarily test the control logic that should be implemented on a model scale vessel. Indeed, the proposed tool has been designed for a fully actuated tug...

This paper aims to present a systematic approach to evaluate the parameters affecting the vessel's performances in the target tracking motion control scenario and, for this reason, three guidance laws have been formalised. Such scenario consists of reaching and following a target of which it is only possible to know the instantaneous position...

Dynamic positioning systems are most commonly used in offshore operations. They provide an automated controlling of position and heading of the vessel using its own thrusters to compensate environmental disturbances. The allocation of total required force over the available actuators is a complex task, as DP-systems are over-actuated....

Pool boiling is a pretty well-known benchmark of diffusive system with both practical and theoretical interest. We have investigated Neumann-boundary feedback control by combining the backstepping approach and the circle criterion. Conditions for local/global stability with nonlinear boundary conditions as input are investigated by explicitly...

The article presents a multiphysics modelling approach to design an integrated electric propulsion system for ship dynamic positioning purposes. The simulation platform integrates the model of the shipboard power plant, the hydrodynamic and environmental forces and the dynamic positioning controller. The shipboard power system has been modelled...

In this article, we propose a control-oriented Wiener model for wet-clutches in filled conditions and we discuss the associated identification technique. We design a novel hybrid controller, which ensures zero steady-state error and a fast nonovershooting response. We show that the controller parameters can be conveniently obtained by solving a...
