Abstract

The invention discloses a shore power wireless charging prediction control method and system based on a digital twinborn model, and relates to the technical field of shore power connection of ships berthing in a port. The method comprises the following steps: firstly, constructing a target ship and a digital twin model comprising a ship kinematics sub-model, a sea wave disturbance sub-model and a coupling coefficient mapping sub-model, and acquiring motion attitude data and environmental sea wave data of the target ship in real time; inputting the acquired data into a digital twinborn model to map to obtain a coupling coefficient change track, finally taking the coupling coefficient change track as a feed-forward quantity, constructing a model prediction control optimization problem in combination with a current electrical state parameter, solving to obtain an optimal control quantity sequence, and outputting the first control quantity to shore power wireless charging equipment, thereby realizing wireless charging of the shore power. Therefore, the influence of coil offset caused by ship movement on the transmission efficiency is compensated in advance, accurate prediction and active compensation of coupling coefficient changes caused by ship movement are achieved, and the shore power wireless charging transmission efficiency and dynamic stability are remarkably improved.
