Study on nonlinear characteristics of high-speed maneuvering of underwater vehicle

HU Jinhui;HU Dabin;XIAO Jianbo;College of Power Engineering,Naval University of Engineering;  
Under the condition of strong maneuvering,the phenomena of bifurcation,saltation and multiple solutions may occur to the resolving of underwater vehicle motion model,corresponding to the motion of underwater vehicle,an unstable phenomenon may appear. To solve this problem,the influence of various parameters on the stability of underwater vehicle in high speed is studied according to the theories of the system stability,stability identification and bifurcation,as well as continuation algorithm for high-dimension nonlinear systems. The numerical solution of the bifurcation and other dangerous situations was obtained. The research results can provide a useful guidance for practical operation control of underwater vehicle.
