Abstract:

According to the problem that the spiral callsearch method is only feasible in theory, a novel optimal extended position search method based on improved particle swarm optimization (PSO) algorithm is proposed for the unmanned underwater vehicle (UUV) to search the uniform linear motion target. Firstly, based on the UUV’s search width the model of optimal steering angle is established, and it is optimized by the improved PSO algorithm, then on that basis, another search method with unknown velocity of target is also analyzed. Secondly, several cooperative search methods of formation of the UUV based on different projection are discussed. Finally, the feasibility of the proposed method is proved by the results of simulation, and some suggestions are proposed for future development directions of the UUV.
