The invention discloses an airplane angle-of-attack protection control method. The airplane angle-of-attack protection control method comprises the steps of 1 collecting an airplane signal; 2 calculating a maximum angle-of-attack; 3 calculating an obtained angle-of-attack threshold; 4 calculating a driving rod vertical alarm displacement and an instruction angle-of-attack; 5 obtaining a differential branch signal, a proportion branch signal, an integration branch signal and an integration branch logic operation result; 6 outputting, controlling and stabilizing the larger one of the integration branch signal and the integration branch signal; 7 determining the value of step 6; 8 determining a gain so as to adjust a real angle-of-attack of the airplane; and 9 obtaining a yield value of the differential branch signal, the proportion branch signal and the integration branch signal when the airplane is in different states. Through adoption of the airplane angle-of-attack protection control method, a connectional initial lead of the angle-of-attack protection function can be reduced; the angle-of-attack protection function can be realized; and a good robustness is provided to the system.
