The invention discloses a high-lift system position control method, which comprises the following steps of: reading an airfoil initial angle by a position sensor arranged in a high-lift system, and giving a target angle when an airfoil target moves and is clamped by a flap and slat control handle so as to obtain an airfoil movement angle difference; the transmission shaft stroke is obtained through the ratio of the transmission shaft stroke to the airfoil angle and the fine adjustment amount; an acceleration stage stroke and a deceleration stage can be obtained by using acceleration stage time and deceleration stage time and setting the rotating speed of a transmission shaft at a constant speed stage; based on the total stroke, the strokes of the acceleration stage and the deceleration stage, and the rotating speed and the movement time of the constant-speed stage, obtaining a constant-speed stage stroke, and further obtaining the rotating speed of the transmission shaft in the constant-speed stage; calculating an acceleration-stage stroke and a deceleration-stage stroke based on the rotation speed of the transmission shaft at the constant-speed stage, finally determining a function relationship between the real-time rotation speed and the real-time angle difference of the transmission shaft, and carrying out the position control of the high-lift system according to the function relationship.
