Simulation Research of Full-Ocean-Depth Manned Submersible Based on Experimental Data

The motion simulation of manned submersible plays an important role in the whole submersible development. During the actual operation of manned submersible, it is affected by the factors such as deep ocean current, model uncertainty and unmodeled dynamics, which make the traditional simulation results differ greatly from the actual results. Taking "Fen Douzhe" manned submersible as the research object, the kinematic and dynamic models were established, and the system disturbance was estimated by using long and short term memory neural network, and the model was verified by simulation calculation with the experimental data of "Fen Douzhe". The effectiveness of the simulation method is verified by comparing the simulation results with the actual experimental data.
