A certain type of underwater vehicle is a kind of underwater weapon which can realize the precise guidance and attack to the submarine target. The hoisting of the ship is the key link to realize the launching preparation of the underwater vehicle. In order to improve the intelligence of ship hoisting on board underwater vehicle,an intelligent control technique is proposed based on loading of a load transfer mechanism and adjustment of mechanical parameters of terminal attitude for hoisting manipulator on board. The technical preparation flow and key technology of underwater vehicle loading are analyzed,and the constraint parameter model of pressure control of ship hoisting manipulator is constructed,and the load-transfer mechanism carrying capacity of ship hoisting robot arm on underwater vehicle is analyzed. The moving platform and the power driving unit of the hoisting robot arm are established,and the pressure bearing mechanics control of the ship hoisting arm of the underwater vehicle is carried out by combining the feedback compensation method. The finite element dynamic analysis method is used to construct the control law of the underwater vehicle hoisting arm,to realize the pressure moment control of the underwater vehicle ship hoisting robot arm,and to improve the automatic adjustment ability of the position and posture of the underwater vehicle ship hoisting arm. The simulation results show that the proposed method is more stable for the intelligent control of underwater vehicle hoisting manipulator,and has higher accuracy of position and pose tracking in the process of underwater vehicle hoisting,and improves the safety and intelligence of underwater vehicle loading.
