UAV Path Re-planning of Multi-step Optimization Based on LRTA* Algorithm

Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 173)

Abstract

For the UAV with the flight environment of unknown threats in advance, the paper combine self-learning A* real-time algorithm with node expansion method based on Five-fork Tree, then application of multi-step optimizing search algorithm re-plan path. When the UAV’s detectors detect unknown threats in flight environment, the algorithm modify the affected tracks according to new environmental information in order to get a new track. Finally through a numerical simulation demonstrates the effectiveness of the algorithm.
