Focusing on the actuator fault of the quadrotor unmanned aerial vehicle (QUAV), an active fault-tolerant control scheme based on fixed-time linear active disturbance rejection control is proposed. Firstly, in order to simplify the complex dynamic model, the virtual control quantity is introduced to decouple the flight control system of the QUAV. Secondly, the fixed-time extended state observer (ESO) is utilized to estimate and compensate the internal uncertainty, external disturbance and actuator fault of the QUAV in fixed time. Thirdly, a continuous output feedback controller based on fixed-time ESO is designed to keep the stability of the flight control system with actuator fault and external disturbance. Finally, the closed-loop stability of the flight control system is demonstrated by Lyapunov function. The numerical simulation is carried and the results also verify the effectiveness of the proposed control scheme.

... bances, including gusts of wind and electromagnetic interferences, which not only impede the control precision of the quadrotors but also give rise to various mechanical failures [7]. Therefore, This study aims to identify a control methodology that can mitigate the adverse effects of wind disturbances, minimize the impact of electromagnetic interference-induced sensor failures, and achieve superior quadrotor tracking performance. ...

... In [14], a combination of a fixed-time and sliding mode control observer was designed to effectively deal with ground effects and blade damage in the attitude subsystem. In [15], an active fault-tolerant control scheme based on fixed-time linear self-anti-disturbance control was designed. Based on the homogeneity theory and the Lyapunov stability method, a double-loop fixed-time controller was designed for attitude control in [16]. ...
