Abstract:

In view of the problem of collision avoidance path planning for unmanned surface vessel (USV) in obstacle maps, a static global path planning collision avoidance method based on improved ant colony algorithm and a local path re-planning scheme for unknown obstacles are proposed. The grid method is used to model the obstacle environment. By designing a composite heuristic function, proposing a dynamic pheromone giving mechanism, and introducing a chaotic optimization operator, the problems of traditional ant colony algorithms being prone to falling into local optima and having poor convergence are solved. Furthermore, based on the fish schooling effect, a local path re-planning scheme is proposed to solve the path re-planning problem of USV formations when encountering unknown obstacles. Simulation experiments on a distributed formation system consisting of five USVs are conducted to verify the effectiveness of the proposed method for collision avoidance in formation.

Key words: unmanned surface vessel (USV) formation, path planning, path re-planning, improved ant colony algorithm, chaos optimization
