Auxiliary wing leveling control method for large amphibious aircraft

The embodiment of the invention discloses a wing auxiliary leveling control method for a large amphibious aircraft, which comprises the following steps of: 1, carrying out amplitude limiting and filtering processing on a roll angle and a steering wheel instruction, and obtaining a roll angle speed correction value based on the corrected roll angle; 2, based on the driving intention of a pilot, judging according to the size of the roll angle, determining to keep the current gradient or perform transverse leveling of the wing, and obtaining a corresponding roll angle instruction; step 3, integrating the current roll angle, the roll angle instruction and the roll angle rate damping instruction to obtain a roll keeping control instruction; and step 4, adding the roll angle keeping control instruction into the main flight control law so as to realize a roll angle keeping function. According to the technical scheme provided by the embodiment of the invention, the problem that in the dampening process of an existing
