Guidance of unmanned air vehicles based on fuzzy sets and fixed waypoints

An alternate guidance scheme of unmanned air vehicles based on fuzzy sets and fixed way points was proposed. The use of fuzzy approach was justified by the generating additional intelligence onboard autonomous vehicles. The five-dimensional waypoint-based fuzzy guidance system (FGS) for unmanned aircraft vehicles dealt with unflyable waypoints and driving the aircraft on flyable trajectories that try to cross the waypoints. Computer simulations show that the aircraft correctly crosses all waypoints in the specified order
