The Anti Swing Strategy of Davit System to Unmanned Surface Vehicle at Sea

Aim: ing at the problem that the marine mother ship's davit system cannot accurately and quickly hoist due to wind and waves during the process of recovering the unmanned boat, an anti-swaying gondolas recovery system is designed to realize the automatic hoisting and deployment of the unmanned boat for recovery or deployment. We created a tension-length gondola recovery and deployment system model, which reduced the swing angle of the unmanned boat davit system's hoisting and deployment through adaptive control of the tension and length of the davit ropes, thereby realizing the installation and deployment of unmanned maritime boats at sea. It’s accurate and fast. Simulation experiments show that under the combined action conditions of 10 ° roll angle and 5 ° pitch angle, the deflection range of the gondola system equipped with a deflection device can reach about 60%.
