- Abstract:

This paper proposes an algorithm that combines global and local dynamic path-planning methods to solve the dynamic path-planning problem for unmanned underwater vehicles (UUVs) in near-shore environments. First, a fast-expanding random tree algorithm based on adaptive target guidance is proposed to increase the directionality of random tree growth. The algorithm then achieves rapid convergence using turning and reselection strategies to reduce ineffective expansion. Further, an adaptive sub-node selection strategy is used after obtaining the global path to acquire sub-target points for the dynamic window approach. This approach decomposes the complex global dynamic task planning into multiple simple dynamic path-planning tasks, preventing the dynamic window approach from falling into local minima. Finally, the effectiveness and practicality of the algorithm are verified using simulation experiments of UUV departure tasks.
