Ground taxiing deviation correction and automatic takeoff control laws for civil aircraft
Year: 2025
Type: conference-paper
Abstract: To enhance the autonomy and safety of civil aircraft during takeoff, deviation-correction, pitch tracking, and airspeed tracking control laws are designed based on the civil aircraft ground taxiing model, enabling automatic takeoff from ground taxiing to liftoff. Firstly, a combined correction control law using nose wheel steering and rudder deflection is designed based on this basis, and a power function-shaped influence factor is introduced for control allocation between the two. Secondly, a pitch angle tracking control law is designed for the transition phase from three-wheel to two-wheel ground taxiing. For the liftoff phase, an airspeed tracking control law is designed, with pitch angle as the inner loop and speed as the outer loop. A fade-out device is introduced to enable smooth transitions from the pitch tracking control command to the speed tracking control command. Finally, the effectiveness of the proposed combined correction, pitch tracking, and speed tracking control laws are verified through numerical simulations.
