Abstract
In this paper, a new method of guidance law design for multi-unmanned aerial vehicle (UAV) cooperative ground target circumnavigation is proposed. Unlike existing studies, we consider the process of tracking and cooperation as a composite system. Therefore, the coupling of UAV linear velocity and angular velocity is considered in the design process. A new lemma of a composite system comprising two subsystems that satisfy exponential stability is proposed. Based on this method, a guidance law for the cooperative circumnavigation of a ground moving target by multiple fixed-wing UAVs was designed. Two examples are presented to illustrate the effectiveness of the proposed guidance law.
