Study on Synthesis Optimization of Speed and Seakeeping Performance Based on On-Line Simulation of High-speed Single-hull Ship

摘要

In this paper, the mathematic model of high-speed single-hull ship's propulsion system (adjustable-pitch screw propulsion) is firstly established. Then, based on MATLAB, the simulation model of the propulsion system is built with the help of simulation software-Simulink. And the intelligent control on the propulsion system is carried out by using fuzzy controller of Look-up Table. After that, the mathematic model of synthesis optimization of high-speed single-hull ship is established by considering control, speed and seakeeping performances. Based on forementioned established simulation model and applying GAOT-MATLAB's optimization toolbox for genetic algorithm (GA), the authors carry out the optimization design of the system. At last, the authors have given an example and validated the accuracy and reliability of the simulation and optimization models.
