A Robust Fixed-Time Sliding Mode Control for Quadrotor UAV

This paper proposes a robust algorithm based on fixed-time sliding mode controller (FTSMC) for Quadrotor aircraft. approach is Lyapunov theory, which guarantees system stability. Nonlinear error dynamics techniques are used to achieve accurate trajectory tracking in the presence of disturbances. The performance FTSMC compared with typical non-singular terminal (NTSMC) evaluate its effectiveness. numerical results show that more efficient than NTSMC disturbance reduction.
