Abstract:

Aiming at the defect that the traditional path planning algorithm can only plan a single shortest path and can not adjust the path width, which is difficult to apply to the cluster route planning of autonomous underwater vehicle (AUV), a genetic algorithm based on elite family (EFGA) is proposed. In this algorithm, gene fitness is added to the fitness evaluation function, and elite individuals are marked as the result of multi-path planning in the process of evolution. Based on this algorithm, a multi-agent path planning (MAPP) method is designed for AUV cluster path planning. Simulation results show that the algorithm can solve the conflict free path set, realize MAPP, reduce the navigation time of underwater vehicle cluster by realizing the optimal multi-path navigation scheme of AUV cluster, and meet the requirements of adjustable path width for different AUV formation sizes.

Key words: autonomous underwater vehicle (AUV) swarm, multi-path planning, multi-agent path planning (MAPP), genetic algorithm (GA), elite family strategy
