Sliding Mode Control: An Approach to Control a Quadrotor

This paper describes the synthesis and application of controller based on sliding mode theory to a quad rotor. A PD sliding surface is considered for vertical take-off and landing aircraft, also changes in angles are done, and some disturbances are included. Therefore, the controller can be implemented using a PD controller as the sliding surface, and adding some algebra the complete controller algorithm is presented. The controller is tested by simulations.
