Based on the MATLAB, simulation and optimization platform of USV' propulsion system is built, preliminary optimization and simulation analysis of the USV' intelligent propulsion system are carried out. In this paper, we select the optimization analysis of the system control parameters of the fuzzy control system of the high-speed monohull USV as well as 4 parameters including initial pitch, initial...
Based on a kind of typical high speed monohull vessel, the paper discusses an integrate optimization's method of Synthetical Fundamental Mechanics Characteristic with the materials of some ships and some relevant experience expressions. The authors use the weighted sum of rapidity, sea-keeping ability and maneuverability as the sub-objective function of ship performances; use the weighted sum of static...
Based on a kind of typical high-speed monohull, this paper discussed an overall optimization's method of navigational performance and structure characteristic with the materials of some ships and some relevant experience expressions. In order to compare this method with others, the writer had also made up a software(VC++6.0). The result showed that the inequality hierarchical genetic complex method...
In this paper, a mathematical model of synthetically optimizing mechanics properties for ships is constructed. Basing on delamination, parallel algorithm, genetic algorithm (GA) and chaos algorithm, then a delamination-parallel genetic chaos algorithm basing on delicate variables' segments is advanced. This complex algorithm is programmed by VC++ into software which has a user-friendly graphical interface...
Solving the nonlinear model of an aeroengine is converted to an optimization problem, and thus some optimization search methods can be used. An approach to solving the nonlinear model of an aeroengine by use of the genetic algorithm (GA) is developed. By comparison with N-R algorithm, the accuracy of the values of initial guesses is not required for GA. Especially, the approach developed can be used...
