Abstract

The invention discloses a virtual potential field cooperative obstacle avoidance topology control method based on heterogeneous unmanned aerial vehicle formation. According to the method, the unmanned aerial vehicles are superposed with formation keeping virtual potential fields based on heterogeneous formation datum points according to heterogeneous cluster improved dynamic situation fields, cluster networking communication relations among the heterogeneous unmanned aerial vehicles are integrated, a heterogeneous unmanned aerial vehicle dynamic autonomous cooperative obstacle avoidance control algorithm is adopted, autonomous cooperative obstacle avoidance processing is carried out on multiple static/dynamic obstacles, and the unmanned aerial vehicles are effectively prevented from being damaged. The formation can be dynamically adjusted in real time to adapt to obstacle states of different numbers, different distributions and different dynamic characteristics, a predetermined basic formation is synchronously kept in the obstacle avoidance process, meanwhile, the unmanned aerial vehicle can smoothly bypass obstacles, the problem that the unmanned aerial vehicle falls into a local extreme value is solved, and the unmanned aerial vehicle obstacle avoidance efficiency is improved. And oscillation caused by approaching an obstacle can be avoided, and the global optimum of the system is ensured.

Description

technical field [0001] The invention relates to the technical field of heterogeneous unmanned aerial vehicle swarm communication, in particular to a topology control method for cooperative obstacle avoidance based on a virtual potential field of heterogeneous unmanned aerial vehicle formation. Background technique [0002] A heterogeneous UAV swarm is a multi-node cluster network composed of multiple heterogeneous UAVs (large / small UAVs, etc.) through a specific cluster formation protocol, and each UAV node interacts through the network under a predetermined formation topology. information, complete the cooperative obstacle avoidance of UAVs, and carry out optimal control of communication topology to support the completion of the designated tasks of the cluster. [0003] The formation configuration and group topology changes of heterogeneous UAV swarms have an important impact on the completion of swarm tasks. The existing UAV topology control research is mainly aimed at th...
