Active fault-tolerant control strategy of large civil aircraft under elevator failures

(in lingua inglese)

An AFTC strategy based on model following technique has been proposed in this study for civil aircraft longitudinal control after some elevators fail. By introducing the performance improvement coefficient, AFTC can provide the appropriate controller under elevator faults to achieve the good performance. Implementing the control strategy on B747, the control law is able to track step command preciously without the steady-error. When less two elevators fail, there is no obvious difference whether to utilize the THS in FTCS or not with the increment of amplitude of step command.
