Problems solved by technology

However, the traditional ant colony algorithm has the disadvantage of being premature in the later stage of the algorithm, which leads to premature convergence to the local optimal solution, and cannot obtain the global optimal path. Moreover, the existing optimization algorithm has a slow search speed and cannot meet the real-time path of the UAV. planning requirements

Abstract

The invention discloses a UAV path planning method for an electromagnetic interference environment, and the method can be used to obtain a globally optimal path rapidly. Update of information elements of an ant colony algorithm serves as a point of penetration, the global and searching capabilities of the ant colony algorithm are improved by updating the global and local information elements in the ant colony optimization searching process, the searching speed for the globally optimal path of the algorithm is improved, a new path can be generated rapidly according to new work nodes, real-time path planning of a UAV can be realized, and it is proved that when the method is used to resolve a given object point, generation of an initial track needs 353ms, generation of a new track by changing track points needs 261ms, and rapid track searching and computing are suitable for real-time UAV line-patrol path planning in the real environment. The UAV path planning method can be popularized and applied in the technical field of UAV.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a path planning method for an unmanned aerial vehicle in an electromagnetic interference environment. Background technique [0002] In the actual application of UAV operations such as UAV line inspection and surveying and mapping, due to the requirements of the working environment and job content changes, the ground station needs to re-plan the UAV’s operation path, so a fast and accurate optimization method is required. algorithm. Among the many algorithms of current trajectory planning, the fast and efficient computing power of the heuristic algorithm has been favored by the majority of researchers. Among them, the ant colony algorithm proposed by Dorigo has good dynamics in solving complex combinatorial optimization problems. And robustness, so it was first used to solve TSP (Traveling Salesman Problem) and achieved good results. However, the traditional ant...
