This paper investigates a methodology for autopilot design for an unmanned air vehicle where one of the lateral control surfaces, i.e. the aileron or rudder, becomes jammed and unusable. The autopilot handles the automatic recovery, autonomous guidance and landing of the disabled unmanned aerial vehicle. An accurate nonlinear aircraft model is used to build local flight control laws using loop-shaping to decouple longitudinal and lateral channels. The design is carried out in a way to allow smooth scheduling over the local controllers without losing stability and performance, culminating in a robust emergency autopilot over the full flight envelope. The autopilot is tested on an example distress scenario involving aileron surface jam. It is confirmed through simulations that the autopilot design is capable of resuming safe flight and autonomous navigation under the fault scenario and is able to safely land the unmanned aerial vehicle to a target runway.

This paper presents an experimental research simulator of an Unmanned Aerial Vehicle (UAV) and supporting systems, designed at the Department of Avionics and Control, Rzeszow University of Technology. The research simulator enables hardware-in-the-loop testing of an autopilot, actuators, the ground control station and telemetry modules. Particular hardware blocks can be integrated with real-time environment with the use of a CAN data bus, Ethernet interface and a set of popular serial interfaces. Current experiments support development and hardware-in-the-loop testing of advanced flight control and navigation systems of a small UAV (taking into account both the on-board and the ground segments).
