The preliminary optimization analysis of a high-speed monohull USV's propulsion system

Abstract

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 speed, genetic algebra and disturbance value as variables, summarize the effects of different values of each variable, and finally make a comparative analysis of the adjustable propeller propulsion system of fuzzy control based on optimization with non-optimized. The results show that using genetic algorithm to optimize the parameters of fuzzy control can improve the control performance of the unmanned ship and the control effect is ideal. The results are helpful to the selection of the main parameters of the unmanned ship propulsion system (propeller diameter, surface area ratio, etc.) and are also helpful to the designation of the intelligent propulsion system of USV and selection of its control system.
