An Automatic Landing Control Approach for Naval Aircraft via Backstepping Sliding Mode Trajectory Angle Control

To address the problem of automatic landing for naval aircraft in complex environments, this paper proposes an automatic landing control approach for naval aircraft based on the backstepping sliding mode control. The model of the fixed-wing naval aircraft is established, and its nonlinear longitudinal kinematics and dynamics are analyzed. Additionally, the carrier's motion is taken into consideration, and the stability of the system is verified with the designed controller. Subsequently, the pitch angle controller in the inner loop and the trajectory angle controller in the outer loop are designed according to the integral backstepping sliding model control method. Finally, the simulation demonstrates that the proposed controller exhibits a certain degree of anti-disturbance capability and can achieve the safe landing on the aircraft carrier in the presence of carrier air-wake disturbances.
