Fault tolerant attitude controller for a class of additive faults via High-Order Sliding Modes
Résumé
In this paper, an autopilot for attitude tracking is designed using disturbance compensation techniques. The proposed controller uses backstepping design procedure and combines the feedback linearization technique with high-order sliding-modes based identification for fault tolerant control. System faults and external disturbances are compensated by a differentiable term generated by means of the robust exact high-order sliding-modes differentiator. The control signal generated for the controller does not require filtration. Simulations illustrate the performance of the proposed controller in the rigid body model of an F-16 aircraft.
