Preliminary Study Of Small High-speed USV Navigation Performance Comprehensive Optimization Method

This paper in typical high-speed monohull and trimaran USV as the foundation,according to some of the material and related experience analysis formulas and combinedwith the characteristics of the high-speed USV, discusses the performance of high-speedUSV navigation comprehensive optimization design.First established in high-speed monohull USV rapidity optimization, improvedreliability optimization and wave resistance optimization of the mathematical models, andalso includes the three aspects of the optimization variables, target function and constraints.This paper chose genetic algorithm as the optimized algorithm, and use of the C++languageof high-speed monohull USV navigation performance comprehensive optimization program.A lot of calculations data indicate that the genetic algorithm in multiple targets, and theconstraint variables on engineering problems have very good use value.Second according to the characteristics of high-speed trimaran USV, I decided itsrapidity mathematical model of optimization. According to drag resistance test data, Icompiled the residual resistance factor calculation programs, and on the basis of high-speedtrimaran USV rapidity performance of comprehensive optimization calculation.Finally I discussed the two sets of optimization program’s stability algebra, analyzeshigh-speed monohull USV sailing performance general objective function values andhigh-speed trimaran USV rapidity objective function values with the speed anddisplacement of changes the curves, this paper discusses the different weight distribution ofhigh-speed monohull USV navigation performance general objective function valuesinfluence.Through the above steps, I compiled a set of high-speed monohull USV navigationperformance comprehensive optimization program and a set of high-speed trimaran USVrapidity comprehensive optimization program, through a large number of results show thatthe programs are stable and reliable. This paper provides a reference platform forhigh-speed USV’s preliminary design.
