The control algorithm combines the robust backstepping sliding mode manage algorithm inside the feedback manage structure to successfully guarantee the trajectory tracking capability with the desired position and attitude. Via Lyapunov stability analysis, the stability and overall performance of your handle method of a coaxial twin-rotor aircraft had been studied. Aiming in the influence of parameter uncertainty, external disturbance and sensor noise on the flight of a coaxial rotor UAV model, a simplified 6-DOF dynamic model of an aircraft according to the Newton uler formula is established. A position and attitude feedback manage method based on a robust backstepping sliding mode control algorithm was designed. The stability and performance from the handle technique of a coaxial rotor aircraft have been studied employing a Lyapunov stability evaluation. As outlined by the numerical simulation results under aerodynamic interference and sensor interference, the robust backstepping sliding mode cont.
