Modeling and stability control of underwater high-speed vehicle

For accurate analysis of the motion of underwater high-speed vehicle at a high speed, using the MATLAB, a modularization simulation model of underwater high-speed vehicle was implemented and simulated.

According to the fact that the relative navigation of underwater vehicle and buoy is mainly relied on acoustical transmission,two methods of relative navigation,which are independent of acoustics are put forward.

In order to debug and verify this underwater navigation system,the simulation platform of navigation system for underwater vehicle is developed.

This paper discusses and introduces several kinds of commonly used model of stochastic differential equation and the method of solution in the groundwater movement.
