Turning lift compensation control method for large amphibious four-engine turboprop aircraft

The embodiment of the invention discloses a turning lift compensation control method for a large amphibious four-engine turboprop aircraft, which comprises the following steps of: 1, calculating and generating a roll angle comprehensive instruction according to a roll angle, a roll angle speed and a pitch angle; 2, according to the roll angle, the roll angle speed, the pitch angle and the roll angle comprehensive instruction obtained through calculation in the step 1, a turning lift force compensation instruction during turning of the aircraft is obtained through calculation; wherein in the process of calculating the turning lift compensation instruction in the step 2, asymmetric correction is carried out on the lift compensation amount of left and right rolling of the aircraft, so that the influence of slip flow of the four turboprop engines on aerodynamic force of the aircraft is counteracted. According to the technical scheme provided by the embodiment of the invention, the problem that the flight safety i
