Abstract

Abstract: The process of wingtip docking in composite aircraft is challenged by significant unsteady vortex aerodynamic disturbances arising from the close-range coupling of wingtips, thereby posing considerable constraints on docking precision and flight safety. This study endeavors to address the intricate task of airborne wingtip docking control amidst wingtip vortex disturbances through a comprehensive investigation of airborne wingtip docking control technology, grounded in the tenets of active disturbance rejection control (ADRC) theory. Initially, a mathematical model encapsulating the dynamics of three-channel attitude/displacement during the docking operation, incorporating both the wingtip docking mechanism and the wingtip vortex model, is established. Subsequently, a guidance law based on the nonlinear L1 method and an ADRC-based attitude controller based on dynamic inversion have been designed to mitigate the effects of wingtip vortex disturbances and enhance docking control robustness. An extended state observer is employed to monitor the state and disturbances of the disturbed aircraft, while nonlinear state error feedback is utilized to compensate for observed disturbances. The efficacy of the proposed ADRC-based composite aircraft wingtip docking control methodology is validated through simulation, demonstrating its capability to achieve rapid and stable wingtip docking amidst wingtip vortex disturbances.
