Aircraft automatic landing control technology faces several challenges, including the complexity of nonlinear dynamic modeling, inadequate response to external environmental disturbances (such as wind speed), the difficulty of multivariable control, and the difficulty of meeting high-precision control requirements. To address these issues, this paper proposes an automatic landing control system based on a longitudinal-lateral collaborative hierarchical control strategy, with a focus on the fixed-wing twin-engine transport aircraft. The nonlinear mathematical models of its longitudinal and lateral motion are constructed. Unlike traditional independent longitudinal or lateral control strategies, this approach combines classical Proportional-Integral-Derivative (PID) control and Model Predictive Control (MPC), where the outer-loop PID controller is responsible for trajectory tracking and the inner-loop MPC controller optimizes attitude control, fully leveraging the advantages of both in terms of dynamic response and steady-state performance. This longitudinal-lateral collaborative hierarchical control method effectively addresses flight path deviations and attitude changes while ensuring stable landings under complex meteorological conditions, such as crosswinds and turbulence. Simulation results demonstrate that, compared to traditional single control methods, the proposed strategy not only improves the system's robustness and stability in complex environments but also optimizes energy efficiency, offering high adaptability and real-time performance suitable for a wide range of practical flight missions. This research provides new theoretical support for automatic landing technology in fixed-wing aircraft and offers strong support for the design and implementation of next-generation intelligent flight control systems.
