| چکیده مقاله |
| This paper addresses the application of a Super Twisting Sliding Mode Controller (STSMC) for the precise tracking control of a rudderless flying-wing UAV. The flying-wing UAVs are equipped with elevons as bi-functional control surfaces which serve as elevator and aileron control surfaces simultaneously. They are known for their unique aerodynamic characteristics and pose challenges in terms of control system design due to their unconventional characteristics and lack of horizontal or vertical stabilizers. Furthermore, the efficient utilization of available control inputs becomes a critical consideration. Optimizing the control surfaces and propulsion system to achieve the desired maneuverability without conventional control surfaces, requires innovative approaches in control system design. The proposed control strategy aims to enhance the UAV stability and maneuverability in longitudinal channel with the focus on tracking control of angle of attack and altitude, by taking advantage of the robustness features of super twisting sliding mode control. The method is preferred for its ability to design robust tracking controllers, making it well-suited for addressing the aerodynamic complexities associated with the rudderless flying-wing UAVs. Simulation results demonstrate the effectiveness of the proposed controller in achieving precise trajectory tracking and disturbance rejection with reasonable control energy costs, thereby showcasing its potential for real-world implementation in unmanned aerial systems. |
