Abstract

In this paper a UAV guidance law for tracking circular paths based on proportional navigation is developed. It is shown that when gradient information is available, the UAV an perform a gradient descent search operation in a given area of interest by suitably electing its heading direction. The guidance law is further extended to cooperating muliple UAVs. Using repulsive potential functions, it is shown that the UAVs can locate multiple maxima/minima in the search region. A complete Lyapunov stability analysis of he guidance law in the horizontal plane is performed to prove asymptotic stability for all nitial conditions. Numerical simulations are presented to show the circular path tracking and gradient search capability of the guidance law.
