Abstract:

Aiming at the problems of communication delay and easy failure of a single autonomous underwater vehicle (AUV) in underwater cooperative search, a new method using distributed cooperative structure and rolling optimization strategy is proposed, which optimizes the objective function based on target existence probability, environmental uncertainty and coordinative pheromone by using the improved brain storm optimization(BSO) algorithm. Simulation results show that the proposed method can avoid collision and still be able to search all targets in the case of communication delay. Through simulation, the recommended value range of key parameters of the proposed method is given, and it is verified that the failure of individual AUV in the search process has little impact on the overall search effect, and the method has strong real-time and robustness.

Key words: autonomous underwater vehicle (AUV), cooperative search, coordination pheromone, improved brain storm optimization (BSO) algorithm
