Abstract:

High-quality path is an important prerequisite for future unmanned autonomous combat. A path planning method based on potential-field enhanced fireworks algorithm (PEFWA) is proposed for the path planning in complex obstacle environment. A planning space model and a dynamic dimension path description model are established, and an objective function including the feasibility factor and the length factor is set up to transform the path planning problem into an optimization problem. A dynamic dimension fireworks initialization strategy and a dimension adding and deleting strategy are designed to make the adjacent dimension individuals meet the distance constraint. An explosion amplitude calculation method and a continuous dimension selection method based on obstacle space information are proposed to generate the improved explosion sparks foe improving the global search ability. A potential field is generated to enhance the explosion spark by introducing the potential field guidance strategy, and the selected dimension is searched for many times in the direction of resultant force to improve the local optimization ability. The cross-combination strategy is used to generate the mutation sparks, and the dimensional individuals beyond the planning space are deleted to improve the efficient generation ability of diversity fireworks. A double-layer tournament selection strategy based on cosine similarity is proposed to improve the continuation ability of fireworks features. The same benchmark function is used to compare PEFWA with fireworks algorithm (FWA), particle swarm optimization (PSO) algorithm and genetic algorithm (GA). The results show that the optimization performance of PEFWA is stronger. Multiple path planning simulation experiments were carried out in the same complex obstacle environment to verify the effectiveness of each module in PEFWA. Compared with PSO, GA and A* algorithms, PEFWA has the advantages in planning success rate, path length, path smoothness and robustness of results. PEFWA is effective for two-dimensional global path planning.
