Abstract This chapter presents a guidance algorithm for a UAV. It combines a nonlinear lateral guidance control law, originally designed for UAVs tracking circles for mid-air rendezvous, with a new simple adaptive path-planning algorithm. Preflight path planning consists only of storing a few waypoints guiding the aircraft to its targets. The chapter presents an efficient way to model no-fly zones (NFZ), to generate a path in real time to avoid known or “pop-up” obstacles, and to reconfigure the flight path in the event of reduced aircraft performance. Simulation results show the good performance of this reconfigurable guidance system which, moreover, is computationally efficient [1, 2].
