- Abstract:
-
Ocean currents, which have a substantial impact on the navigation of low-speed, underdriven AUVs, can increase navigation time, raise energy consumption, and change the navigation trajectory. Therefore, planning an optimal navigation route that accounts for the disturbance of ocean currents is of considerable importance. This study mainly analyzes the mechanism by which ocean currents influence AUVs and proposes an improved DQN path planning algorithm based on the prioritized experience replay method. This modification addresses the problem of overestimation, which is a common issue when using a traditional DQN path planning algorithm. Additionally, the action design and reward functions are optimized. Path planning simulations are conducted in a 3D ocean environment, which is established based on S57 chart data and ocean current data provided by Earth & Space Research. Experimental results show that the improved DQN algorithm generates a more effective global path planning, offering a navigation route that minimizes time and energy consumption. This work provides a valuable reference for underwater AUV navigation, fully considering the impact of ocean current disturbances.
