Optimal Trajectory Planning of Ship Propulsion System during Ship Speed Control

Optimal Control of Double Star Synchronous Machine for the Ship Electric Propulsion System

this work focuses on modelling, optimal control and numerical simulation of the ship electric propulsion system provided by a double star synchronous machine. The in-depth analysis of the operation of the propulsion system of the vessel allowed us to model elements of the propulsion system. Thus, a non-linear global model was obtained describing the operation of the entire propulsion system. Th...

hydrodynamic performance of the modern ship propulsion system

this paper presents numerical calculations for podded propulsion system using vortex theory and potential panel method. the method discretizes the surface boundary of the body (propeller +pod+strut) and obtained the vortex and propeller surface and potential on strut and pod. a model propeller and strut are considered for these calculations and the results of pressure distribution, flow field a...

Modeling of Ship Propulsion Performance

Full scale measurements of the propulsion power, ship speed, wind speed and direction, sea and air temperature, from four different loading conditions has been used to train a neural network for prediction of propulsion power. The network was able to predict the propulsion power with accuracy between 0.8-2.8%, which is about the same accuracy as for the measurements. The methods developed are i...

Model identification and dynamic analysis of ship propulsion shaft lines

Dynamic response analysis of mechanical structures is usually performed by adopting numerical/analytical models. Finite element (FE) modeling as a numerical approach plays an important role in dynamic response analysis of complex structures. The calculated dynamic responses from FE analysis are only reliable if accurate FE models are used. There are many elements in real mechanical structures w...
