The invention discloses a self-adaptive compensation control method for an aircraft
control system under multi-
azimuth turbulent
wind disturbance. The method comprises steps that 1, according to transverse and longitudinal motion models of an aircraft
control system in the prior art, on the basis that the dominant
wind direction of turbulence disturbance is determined, and a disturbance model corresponding to an aircraft when the aircraft encounters turbulence disturbance of different dominant wind directions is established and used for representing transverse and longitudinal motion models ofthe aircraft at the moment; 2, a general input-output
system model is adopted to represent transverse, lateral and longitudinal motion models of the aircraft when turbulence disturbance of differentprevailing wind directions occurs; 3, based on an
index function used for establishing a piecewise function, an input-output
system model is established based on time
slicing; 4, that the existing aircraft
control system parameters and turbulence disturbance parameters are known are assumed, a nominal controller is established according to the known conditions; 5, that existing aircraft control
system parameters and turbulence disturbance parameters are unknown are assumed, and a self-adaptive controller is established according to the known conditions. The method is advantaged in that the aircraft control system can be effectively ensured to realize expected closed-
loop stability and output tracking performance when encountering the turbulence disturbance alternate influence of a plurality of predominant wind directions so that the safe flight of the aircraft is realized.
