An evaluation of UAV path following algorithms

Path following is the simplest desired autonomous navigation capability for UAVs. Several approaches have been developed in the literature for path following. However, there is no adequate information on the comparison analysis of these algorithms. In this paper, we compare five path following algorithms that are easy to implement, take less implementation time and are robust to disturbances. The comparison of these guidance laws is carried out through simulations using the total cross-track error and control effort performance metrics.
