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.
