Abstract

In this paper, we design a passive fault tolerant control strategy for an uncertain MIMO aircraft model F-18. A novel variable structure controller with sliding surface and Lyapunov function is proposed in order to eliminate the effect of certain type of pre-specified faults. The main features of the proposed control strategy are its simplicity and robustness against uncertainties and parameter variations and some pre-specified faults. Computer experiments illustrating the application of the proposed approach to the longitudinal flight control of an F-18 aircraft model are presented to show the effectiveness of the design method.
