Abstract:

A trajectory planning method based on velocity pausing particle swarm optimization (VPPSO) algorithm is proposed for unmanned aerial vehicle (UAV) trajectory planning in complex multi-threat environments. Firstly, an objective function set is formulated that comprehensively considers the optimality and safety requirements of UAV operation, transforming UAV trajectory planning into a multi-objective optimization problem. Secondly, the introduction of velocity pausing strategy, double group strategy, and velocity equation improvement strategy in the standard particle swarm optimization algorithm effectively balances the global exploration and local development capabilities of the algorithm. Finally, the optimization performance of the VPPSO algorithm is validated using standard test functions and applied to the three-dimensional trajectory planning of UAV. The experimental results show that the VPPSO algorithm has strong global optimization ability, and the planned trajectory results have the best performance in the comparison algorithms.

Key words: unmanned aerial vehicle (UAV), trajectory planning, velocity pausing particle swarm optimization (VPPSO) algorithm, double group strategy
