Fault Tolerant Flight Control System Design for UAV's Using Nonlinear Model Predictive Control

A design for a reconfigurable fault tolerant flight control system for an unmanned air vehicle has been proposed in this p·aper. Due to the severe nonlinearitics inherent in an aircraft system Non-Linear Model Predictive Control has been chosen for the controller design. The results obtained show good aircraft pel'f'ormance in the event of a control surface failure.
