Load constant current control method of wireless charging system of underwater sneaking device

Abstract

The invention relates to a load constant current control method of a wireless charging system of an underwater sneaking device and aims to realize constant control on current of a wireless charging load of the underwater sneaking device in a charging process. The method comprises steps that a neural network algorithm is employed to obtain the duty ratio of a booster switch at the previous moment and change amount of the duty ratio at the previous moment relative to a duty ratio of the present moment; the duty ratio of the booster switch at the previous moment is added to the change amount to acquire the duty ratio, and the booster switch is driven. According to the method, on the basis of the neural network algorithm, in combination with influence of the seawater environment on the charging system, the load output current is detected timely, the load output current is guaranteed to be stable, and thereby application demands of the deep sea environment are satisfied.

Description

technical field [0001] The invention belongs to the field of wireless charging, in particular to a load constant current control method of a wireless charging system of an underwater submersible. Background technique [0002] Autonomous underwater vehicles are an important tool for exploring the underwater world. They are widely used in commercial and civilian fields, as well as in the fields of military and marine environmental science. However, due to the limitations of their own size and battery technology, AUVs cannot work underwater for a long time. , mainly adopts the method of salvaging and recycling to the mother ship for charging, which not only reduces the intelligence, but also is cumbersome and time-consuming, which greatly reduces the working efficiency and concealment of the AUV. Non-contact inductive power transmission technology is an ideal way of underwater power transmission. [0003] Most of the existing wireless charging constant current control systems ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing wireless charging constant current control systems are only suitable for the air environment due to the lack of consideration of many factors affecting the seawater environment such as ocean currents, and cannot meet the needs of complex and changeable underwater environments.

Due to uncertain factors such as nonlinearity and time invariance of the IPT system, it is difficult to establish complex mathematical models, and traditional methods such as PID controllers are difficult to achieve ideal control effects
