AI Technical Summary

Technical Problem

Existing UUV depth control methods are prone to overshoot or oscillation in high-speed maneuvering missions, and the parameter tuning process of PID controllers is time-consuming and complex, making it difficult to meet the requirements of rapid response.

Method used

By employing an exhaustive algorithm and calibration table, and by setting the initial depth, target depth, and rotational speed information, a stable pitch value and the first rudder angle are recommended. Combining the exhaustive algorithm and the rudder angle combinations in the calibration table, rapid depth-changing control of the underwater unmanned vehicle is achieved.

Benefits of technology

It achieves a depth control accuracy of ±0.2 meters for underwater unmanned vehicles in rapid maneuvering missions, reducing the time consumption by more than 50%. The calibration table is applicable to missions at different speeds and depths, improving mission planning efficiency.
