Sažetak

In this paper, a robust output tracking controller for the quadrotor helicopter is proposed. The proposed controller requires the measurement of only four state variables: positions in the inertial coordinate frame and the yaw angle. Also, the controller is robust with respect to the unmodelled dynamics and provides rejections of all external force and torque disturbances. The effectiveness of the proposed controller is tested on a simulation example of a quadrotor tracking under the influence of wind which is modelled as unmatched external force disturbances in the horizontal plane.
