DESIGN THE GUIDANCE LAW FOR FORMATION FLIGHT OF MULTIPLE UAVS

摘要

In this paper, the algorithm for theformation flight is designed. In these days, UAVsare actively utilized in battlefield and civil area.In this point, many researches on multiple UAVsoperation has been studied for various missions.In fact, formation flight gives various benefitssuch as high efficiency in aerodynamics and lowexposure rate by opponent's radar. In this paper,the formation flight algorithm is designed basedon the leader-follower method so that it isexpandable to the change of number of operatingUAVs. Virtual Pursuit Point concept is adaptedto design guidance law and it needs only littlecomputing power for real-time operation.Finally, the proposed formation flight algorithmis validated by MATLAB /Simulink environmentsimulation. Designed algorithm shows not onlyprecise formation tracking performance but alsoexpandability to the various number of operationUAVs.
