Fault tolerant control based on adaptive control allocation with a multiple effectors aircraft application

In this paper, a new fault tolerant control method based on adaptive control allocation is presented for a class of unknown actuator faults of the multiple effectors aircraft. In the event of failures, only the control allocation matrix and fault estimate matrix are adjusted on line using the state tracking error, whereas the flight control law named as baseline control law keeps unchanged. The updated laws of the two matrixes are derived based on Lyapunov stability theory. A simulation example of multiple effectors aircraft model shows satisfactory results for the actuator fault tolerant.
