A Guidance System for Unmanned Air Vehicles based on fuzzy Sets and fixed Waypoints

The problem of guidance and control of unmanned aerial vehicles (UAVs) has become a topic of research in recent years. Typical projected UAV operations such as surveillance, payload delivery, and search and rescue can be addressed by waypoint-based guidance. Automatic target recognition, for instance, requires that the aircraft approach the possible target from one or more desired directions. In a highly dynamic cooperative UAV environment, the management system, either centralized or decentralized, may switch the waypoint set rapidly to change an aircraft mission depending on external events, pop-up threats, etc.; the new waypoint set may be ill-formed in terms of flyability (maximum turn rates, descent speed, acceleration, etc.).
