Abstract:

In view of the unmanned aerial vehicle (UAV) three-dimensional path planning problem, an enhanced multi-strategy dung beetle algorithm of UAV path planning is proposed. Firstly, constraints on the flight proximity rate and response time are introduced and added to the threat cost, considering the influence of UAV turning performance, a three-dimensional task space model and trajectory cost function are established. Secondly, the dung beetle algorithm is enhanced by introducing offset estimation strategy, variable spiral search strategy, quasi-inverse learning strategy, and dimensional mutation strategy to improve the algorithm's global optimization capability and convergence speed. Finally, simulation results of the improved algorithm for three-dimensional trajectory planning in an environment are presented. Results demonstrate that by considering both the maneuverability and turning performance of the UAV, the planned path can safely and efficiently avoid hazards. Compared to other algorithms, the enhanced multi-strategy dung beetle algorithm shows better optimization capability and generates higher-quality trajectories.

Key words: unmanned aerial vehicle (UAV), path planning, flight proximity rate, dung beetle optimizer algorithm
