In this article, a sliding mode control scheme is proposed for a quadrotor in the presence of an exogenous disturbance. A nonlinear sliding mode surface is constructed based on the estimate output of a disturbance observer to reject the effect of the unknown disturbance in the quadrotor. The desired control performance is achieved by bringing the state from unstable state to stable ones. To show the effectiveness of the developed control scheme, simulation results are provided for illustration of the designed controller based on disturbance observer.
