Abstract
Guidance laws are proposed to enable unmanned aerial vehicles (UAVs) to accomplish stationary target observation missions. In this paper, a nonlinear guidance law is designed utilizing the characteristics of distance error dynamics. The turning direction of the UAVs is very important for multiple UAVs operation. The turning direction of UAV is related to the line-of-sight angular acceleration of the UAV. The proposed guidance law is analyzed to provide a guideline for selecting guidance gains taking into consideration the turning direction. Numerical simulations are performed to verify the performance of the proposed guidance law.
