A worldwide civil aviation accident survey for the period of 2002 till 2011, conducted by the CAA-UK shows that in this time period nearly 40% of all the aircraft accidents involved loss of control. Despite the fatal outcomes, reconfigurable flight control might have been able to recover the aircraft by efficiently utilizing the remaining control inputs. This research focuses on the application and the evaluation of a model-independent fault-tolerant Sensor-Based Nonlinear Dynamic Inversion NDI (SB-NDI) attitude rate controller. The inner loop of this controller incorporates Hovakimyan’s Approximate Dynamic Inversion controller within the NDI framework in combination with Lyapunov stability, making the controller fully model independent. The inner loop of the controller is complemented with an NDI-based outer loop in order to control the attitude rates. The fault-tolerant capabilities of the designed controller are evaluated with a proof-of-concept flight simulation in the SIMONA Research Simulator. The results of this evaluation indicate that the designed multi-loop SB-NDI controller is not only capable of extending the survivability of the aircraft when compared with a conventional NDI attitude rate controller with a fixed aerodynamic model, it also indicates that it requires a similar physical effort for a post-failure aircraft as an aircraft without failures.
