The problem of localization and encirclement control a moving target by multi unmanned aerial vehicles (UAVs) is considered in this paper. main objective to guide the UAVs form evenly spaced formations along circumference, with centre circumference tracking movement target. Firstly, each UAV assumed only obtain bearing angle information target, for which an estimator developed localize measurem...

Among the various applications for fleets of UAVs, searching and tracking mobile targets remains a challenging task. In this paper, distributed set-membership estimation control scheme is presented. This relies on description uncertainty noise as bounded processes. Constraints field view, well presence false targets, are taken into account. Each UAV maintains several set estimates: one each det...
