OPTIMIZING FUZZY CONTROLLER OF ENGINEERING SHIP WITH GENETIC ALGORITHM

摘要

Adjusting the length of anchor chain controls the course of engineering ship. It limits the moving scope of the ship and makes it not drift about wantonly. But while moving and mooring the ship, because wind, wave, flow and various kinds of random influence is difficult to be predicted, it is difficult to control of the course. So fuzzy controller is used to improve the performance of control in this thesis, and genetic algorithm is adopted to optimize the rule of fuzzy controller, which enables the controller to produce the better result in case of no priori knowledge. Finally, the mathematics model of the ship is set up and simulation is carried on to the system.
