Semi-physical Simulation System For Ship Motion

As the overland test base of ship motion control system, Semi-physical simulation system for ship motion can quicken the exploitation of product, reduce cost and save manpower and material resources. The main content of this paper is for the system.First, the paper introduced the methods of establishing ship's motional model and the models of ambient interference such as wind, ocean wave and stream.Secondly, the paper introduced the composition of Semi-physical simulation system in the mass and the realization methods of every component's functions. Afterward the paper introduced the designed ways of tow subsystem: Information management organ of ship motion and Emulation produce organ of ship motion, and made emulations of ship's motional model and the models of ambient interference.Lastly, the fifth chapter studied the application of fuzzy control in ship's heading control. The main substance of the part is the designing of four types of fuzzy controller: Fuzzy controller of PD type, Fuzzy controller of PD type - Proportion multiple controller, Fuzzy model reference learning controller and Double stage fuzzy controller, and made emulation study of their controlling fruitage.
