A Tangential Guidance Logic for Virtual Target Based Path Following
Shantanu Thakar, Ashwini Ratnoo · 2017
A new guidance logic for UAV path following using a virtual target is presented. With respect to the line-of-sight, the UAV maintains an equal and opposite lead angle as that of the virtual target. A linear analysis of the resulting error dynamics presents a faster convergence to straight line path as compared to existing methods. With no overshoot in the response, the method presents a smooth following trajectory. Comparative simulations are carried out complying with the analytic findings.
