The invention relates to a method for calculating attack angle correction, a stall protection method and a stall protection system. The method for calculating the attack angle correction comprises the following steps: 1, judging whether a lateral overload value needs to be corrected based on a left side local attack angle value, a right side local attack angle value and the lateral overload value, and when a difference value obtained by subtracting the right side local attack angle value from the left side local attack angle value is greater than 0, if the lateral overload value is greater than or equal to 0, judging whether the lateral overload value needs to be corrected; if the lateral overload value is greater than 0, the lateral overload value is not corrected, and if the lateral overload value is less than 0, the lateral overload value is corrected, and if the difference between the right local angle-of-attack value and the left local angle-of-attack value is less than or equal to 0, the lateral overload value is not corrected if the lateral overload value is less than or equal to 0, and if the lateral overload value is greater than 0, the lateral overload value is not corrected if the lateral overload value is less than or equal to 0. If yes, correcting the lateral overload value; and 2, calculating the angle-of-attack correction by using the lateral overload value.
本发明涉及计算迎角修正量的方法、失速保护方法和失速保护系统。计算迎角修正量的方法包括:第一步骤,基于左侧局部迎角值、右侧局部迎角值和侧向过载值判断是否需要对侧向过载值进行修正,当左侧局部迎角值减去右侧局部迎角值的差值大于0时,如果侧向过载值大于等于0,则不对侧向过载值进行修正,并且如果侧向过载值小于0,则对侧向过载值进行修正,并且当右侧局部迎角值减去左侧局部迎角值的差值小于等于0时,如果侧向过载值小于等于0,则不对侧向过载值进行修正,并且如果侧向过载值大于0,则对侧向过载值进行修正;第二步骤,采用侧向过载值来计算迎角修正量。
