“…Among various adaptive fault tolerant control methods for nonlinear systems, the incremental nonlinear dynamic inversion (INDI) control [16,17] has been intensively applied to different types of aircraft. The INDI method can be considered as an incremental form of the widely used feedback linearization approach [18,19]. The advantage of the INDI method is that it makes the controller significantly less sensitive to model mismatch with simpler control design.…”

In this paper, an online flight envelope protection system is developed and implemented on impaired aircraft with structural damage. The whole protection system is designed to be a closed-loop of several subsystems , including system identification, damage classification, flight-envelope prediction and fault-tolerant control. Based on the information given by damage classification, the flight envelopes are explicitly retrieved and processed online from the database and fed into the fault-tolerant controller, which makes the protection system adaptive to a wide range of abnormal conditions. Simulation results show that with envelope protection, loss-ofcontrol accidents are more likely to be prevented, since both the controller and pilots are aware of the shrunken flight envelopes after damage and excessive commands are restricted. In this way, the fault-tolerance of the impaired aircraft can be effectively enhanced.

“…However, the high accuracy of splines in terms of their residuals is opposed by their computational costs for further analytical investigation. Multi-variate splines have been used in, among others, [18,19] in order to model full-envelope aerodynamics.…”

“…However, the estimation of suitable switching surfaces or joints for the piecewise functions usually adds computational difficulty and load [14][15][16][17]. Later, multivariate splines were introduced [18,19]; using simplices and baryocentric coordinates for the base, the so-called B-splines bear the advantage of generalized continuity, dimensional flexibility, and efficient evaluation as well as a stable local basis [20]. Recently, a further approach combining splines with fuzzy logic has been presented in [21].…”
