Additionally, it is presumed that the non-linear system may be faulty, i.e., affected by actuator and sensor faults along with the disturbances, simultaneously. Accordingly, the stability of the robust observer as well as the fault-tolerant tracking controller is achieved by using the H[infinity sign] approach. Furthermore, unknown actuator and sensor faults and states are bounded by the uncertainty intervals for estimation quality assessment as well as reliable fault diagnosis.}, abstract={This means that narrow intervals accompany better estimation quality. Thus, to cope with the above difficulty, it is assumed that the disturbances are over-bounded by an ellipsoid. Consequently, the performance and correctness of the proposed fault-tolerant tracking control scheme are verified by using a non-linear twin-rotor aerodynamical laboratory system.}, type={artykuł}, title={Fault-tolerant tracking control for a non-linear twin-rotor system under ellipsoidal bounding}, keywords={fault-tolerant control, simultaneous faults, external disturbances, non-linear system, robust fault estimation, fault detection and diagnosis}, }
