在 4自由度运动定位的基础上 ,提出以 5自由度代替自由度空间运动的设想 ,解决在失事艇姿态为斜卧时对接问题 ,从而避免救生艇进行有横倾的运动 ,减轻操艇员复杂的操作负担 .文章从立体几何的角度和神经网络控制的角度阐述该设想的可行性 ,并给出计算机仿真结果 Based on the 4-DOF kinematic positioning, the idea of ​​5-DOF instead of the freedom degree space motion is proposed to solve the problem of docking when the stance of the stray boat is in a reclining position so as to avoid the lifeboat from having a heeling motion and to reduce the complexity of the pilot crew The author puts forward the feasibility of this assumption from the perspective of solid geometry and neural network control and gives the computer simulation results
