This paper proposes a distributed vector field control method with an annular virtual tube to achieve continuous encircling and monitoring of a target by multiple UAVs. Simulations and experiments are conducted to demonstrate the effectiveness of the method.
Continuously encircling and monitoring an individual static target is an important application scenario for a multi-UAV system. In this paper, to address the problem of multi-UAV encircling the target arbitrarily, evenly and densely in 3D space, a distributed vector field control method with an annular virtual tube is proposed. Some Lyapunov-like functions are designed elaborately, and a formal analysis based on the invariant set theorem is made to show that all UAVs can complete the encirclement task successfully. Simulations and experiments are carried out to show the effectiveness of the proposed method.(c) 2022 Elsevier Masson SAS. All rights reserved.
