Abstract
The flight control system is a safety-critical component of an UAV and hence shouldinclude a level of fault detection (FD) and controller reconfiguration to be used in casea faulty condition is declared. This paper reports the design of an FD system for the lateral channel of an UAV. The main theoretical contribution is a new threshold function that enhances the fault detection capabilities in the face of substantial model uncertainty. Simulation results show that the new threshold function in combination with a fault detection filter can detect a fault in the lateral channel of an UAV flight control.
