Fractional-order nonsingular terminal sliding mode controller for a quadrotor with disturbances

This paper proposes a finite-time controller for an unmanned aerial vehicle in the presence of Figures/uncertainties using fractional-order terminal sliding mode. First, contrary to existing backstepping mode controllers, this introduces new control approach quadrotor position control, which is based on fast control. Using appropriate surface, tracking error converges zero finite time while providing good robustness properties different complex path scenarios under unknown disturbances. Then, novel scheme developed attitude provides terms against disturbances, and convergence time, etc. Finally, simulation results are presented discuss advantages hybrid proposed work quadrotors disturbances compared other controllers.
