Standoff Target Tracking using a Vector Field for Multiple Unmanned Aircrafts

Journal of Intelligent & Robotic Systems, 2012
This paper presents strategies for standoff target tracking by a team of unmanned aircrafts using vector field. Many methods to the vector field approach were investigated in other papers, but a modified vector field is introduced to obtain new interesting characteristics in this paper. The modified vector field satisfies more constraints. We introduce

Coordinated standoff tracking of moving targets with optimal measurement configuration

2016 13th International Computer Conference on Wavelet Active Media Technology and Information Processing (ICCWAMTIP), 2016
Coordinated target tracking is one of the most important applications in multiple UAVs cooperative control, and coordinated standoff tracking of random moving targets is presented in this paper. Based on the Fisher Information Matrix (FIM), an analytical one-step determinant of FIM is introduced, and the optimal measurement configuration in cooperative

Cooperative Control of Multiple Unmanned Aircraft for Standoff Tracking of a Moving Target

Journal of the Korean Society for Aeronautical & Space Sciences, 2011
This paper presents a cooperative standoff tracking of a moving target using multiple unmanned aircraft. To provide guidance commands, vector fields are designed utilizing the Lyapunov stability theory. A roll angle command is generated to keep a constant distance from the target in a circular motion.

Coordinated Standoff Tracking of Moving Targets Using Lyapunov Guidance Vector Fields

Journal of Guidance, Control, and Dynamics, 2008
This paper presents a control structure for cooperative stand-off line-of-sight tracking of a moving target by a team of unmanned aircraft based on a Lyapunov guidance vector field that produces stable convergence to a circling limit cycle behavior. A guidance vector field is designed for a stationary target and then modified with a correction term ...

Standoff Tracking of a Moving Target for Quadrotor Using Lyapunov Potential Function

International Journal of Control, Automation and Systems, 2019
This paper presents a control scheme for standoff tracking of a ground moving target by a quadrotor unmanned aerial vehicle (UAV). The control system is decoupled into outer loop for position control and inner loop for attitude regulation. In the outer loop design, the standoff motion of the vehicle is described in a cylindrical coordinate system ...

Coordinated Standoff Tracking of a Ground Moving Target and the Phase Separation Problem

2018 International Conference on Unmanned Aircraft Systems (ICUAS), 2018
We extend existing results regarding the kinematics stability of the cooperative standoff tracking of a stationary target by a single UAV as well as a team of UAVs based on a guidance vector field. Furthermore, we examine the so called phase separation problem and by treating simultaneously the convergence toward the desired standoff radius, heading ...
