Abstract:

Aiming at the problem of multi unmanned aerial vehicle(UAV) task planning, based on the bacterial foraging algorithm, the cross-mutation operation of genetic algorithm is combined to perform task assignment. In order to improve the convergence ability of the algorithm, the swimming step length, reproduction times and migration probability of the algorithm are dynamically and adaptively adjusted. A fusion vector field based on the Lyapunov navigation vector field and obstacle avoidance vector field, the real static and dynamic obstacle environment is simulated, and the trajectory planning is completed in the task allocation stage; at the same time, based on the contract network auction algorithm, the task is redistributed after UAV attacked. The simulation results show that, considering static and dynamic obstacles, the task allocation and redistribution of multi-heterogeneous UAVs can be efficiently completed with minimal total cost.

Key words: unmanned aerial vehicle(UAV), task planning, bacterial foraging optimization, contract network
