Intelligent Operation Using Terrain Following Flight in Unmanned Aerial Vehicles

Abstract

A novel approach in terrain following/terrain avoidance (TF/TA) flight is proposed. Due to existing unknown terrain during flight, an intelligent approach is used. Intelligence is implemented using the fuzzy approach. This method can be used in off-line design in trajectory planning which has wide applications in TF/TA maneuvers in unmanned aerial vehicles. A relationship between slope of terrain and aircraft height with speed of aircraft is constructed by fuzzy approach. This work is performed for a two dimensional terrain following flight. This method is state of the art in literature.
