Research on Propulsion Intelligent Control and Systematic Optimization Based on On-line Simulation of Wave-piercing Catamaran

WANG Yi,YANG Songlin,DONG Liang(School of Naval Architecture and Ocean Eng.,Jiangsu University of Science and Technology,Zhenjiang Jiangsu 212003,China)  
To improve the real-time quality in optimization,a method of propulsion intelligent control and systematic optimization for the wave-piercing catamaran based on on-line simulation is introduced.The mathema-(tic) model of the adjustable-pitch screw propulsion is established.The simulation model of the system is then built by means of the simulation software simulink of MATLAB.Intelligent control of the propulsion system is carried out by using the look-up table fuzzy controller.The mathematic model of systematic optimization is then established.The optimal design is carried out with the help of the genetic algorithm toolbox GAOT of MATLAB.Results from the practical example indicate that both accuracy and reliability of the simulation and optimization are good.The method is proved effective and feasible.
