【Abstract】 An efficient and modularized digital simulation software for designing and testing a novel thermal propulsion system of autonomous undersea vehicle(AUVTPS) was developed by using MATLAB/SIMULINK.The AUVTPS was simulated under different regimes of various work stages,and hence the simulation results can be analyzed including the transient characteristics of start process,changing speed process and changing depth process of AUVTPS.This simulation method overcomes the disadvantage of bed test which can only obtain steady characteristics of AUVTPS.The simulation software is used to aid the reliability design of AUVTPS and the robustness design of its control device.This method can be used for some functions of hardware-in-the-loop simulation and bed test,so that the design and development cost can be reduced.更多还原
