Preliminary study on navigation performance optimization analysis of a new type USV and its methods

Consideration on the unmanned surface vehicle (USV) rapidity, maneuverability and anti overturning resistance, this paper creates a synthetical optimization mathematical model of the new USV navigation performance, structure of a complex algorithm, preparation of the related software. Complete a number of optimization calculations, discuss the effects of weight and different speed on the optimization goal, and compared to the optimal performance of single genetic algorithm, hierarchical genetic algorithm and genetic chaotic hierarchical algorithm. The results show that the performance index weight and speed have significant influence on the optimization goal, and hierarchical genetic algorithm optimization performance is better.
