Abstract:

Aiming at the characteristics of energy limitation, high real-time performance, and strong confrontation in underwater dynamic target capture tasks, a two-layer dynamic target capture algorithm is proposed to solve the problems of low efficiency and poor collaboration faced by multi autonomous underwater vehicle (AUV) systems in capture tasks. Firstly, based on the velocity relationship between the pursuer and the target, the Apollonian circle principle is extended to three-dimensional space to make the encirclement more realistic. Secondly, in response to the inherent detection error problem of sonar systems, an adaptive Kalman filter is designed to effectively suppress noise interference while predicting the real-time motion trajectory of the target AUV. Then, reconstruct the neural activity propagation mechanism of Glasius bio-inspired neural network and optimize the decision-making process to improve task execution efficiency. Finally, the effectiveness and superiority of the encirclement algorithm were verified through simulation experiments.

Key words: dynamic target capture, apollonius circle, adaptive Kalman filter, Glasius bio-inspired neural networks
