Abstract:Aiming at the problems of long time consumption,serious fly-around distance and frequent change when UAVs are flying in the airspace,under the condition of conflict between two UAVs,a dual UAV conflict resolution method was proposed based on the game theory.Firstly,a conflict detection model was established based on the kinematic model of two UAVs,then the time formula for the minimum distance between the two UAVs was obtained.According to the formula,the changed speed or heading angle value of the two UAV was reversely solved.Secondly,the suitable extrication strategies for both sides with the expected utility were analyzed by combining the Hawk Dove game with the Bayesian game.Finally,UAVs executed the recovery strategy to return to the initial state in order to reduce the track deviation after conflict resolution.The results show that compared with the single-UAV release,the effect of release time,fly-around distance,total flight time and total flight distance are improved.The improved detection model can not only quickly calculate the change value of the extrication strategies,but also choose the extrication strategies according to their own maximum benefits after introducing the game strategy for both sides.The method is simple and effective in the problem of conflict resolution,which ensures that the UAV can quickly accomplish conflict resolution.
