<p>In this paper, a variable bandwidth active disturbance rejection control (VBADRC) method is proposed for the longitudinal dynamic control of carrier-based aircraft. To address the challenge of reference trajectory tracking under external disturbances, such as carrier air wake, a variable bandwidth extended state observer (VBESO) is designed. The VBESO estimates external disturbances and internal uncertainties, and compensates the disturbances by feedback control. Additionally, an adaptive method is integrated into the feedback controller to adjust parameters in real time, simplifying the parameter tuning process and reducing parameter deviations. The stability of the system is rigorously proven using Lyapunov theory. Finally, the simulation results are compared with linear active disturbance rejection control (LADRC) to verify the effectiveness of the proposed method.</p>
