The dynamics model of missile sealifts system for navy ships connected parallely is established. The dynamics simulation analysis of system is studied. The dynamics characteristic of missile box on the condition of different sea states and place parameters of crane are analyzed. The theory and technology bases for the design of system of missile sealifts or navy ships connected parallely are presented. The controlled multibody system dynamics of the system of missile sealifts with wave compensation for navy ships connected parallely is presented. On the condition of stochastic momevement of depot ship and incept ship and under the action of sealifts and wave compensation, the dynamics of sealifts system is studied by using discrete time transfer matrix method of multibody system. The calculate method of electric machine impule is developed in the process of supplying missile and action of wave compensate. Based on the PLC control system, the control method, which control supply process by testing torque of guide strings is presented.

However, due to disturbances caused by sea wind, sea wave, sea flow and some other uncertainties such as variance of ship physical parameters, how to control autopilots properly is a very difficult problem. An autopilot based on fuzzy logical control is proposed to make a ship follow the virtual course, which is calculated from real course and track deflection.

针对实际航向中，船舶受到来自海风、海浪、海流的干扰和船自身物理参数时常变化使得自动舵的控制变得困难的缺陷，提出了一种基于模糊逻辑控制的自动舵，并提出将期望航向角和航迹偏差共同计算得到的虚拟航向角作为新的期望航向角。
