AI Technical Summary

Technical Problem

Existing position control methods for high-lift systems suffer from insufficient accuracy, especially due to issues such as excessive contraction or expansion of the flap and slat angles under the influence of system inertia. Furthermore, traditional methods place high demands on the system's braking capacity, making them prone to malfunctions.

Method used

A high-lift system position control method is adopted. By adding fine-tuning to the ideal position control law, the speed and position control law is constructed using the ratio of the drive shaft stroke to the airfoil angle and the motion time. Combined with SIGN and MIN functions, precise control is achieved, which can adapt to different load conditions and mechanical clearances and avoid overtravel failures.

Benefits of technology

It improves the position control accuracy of the high-lift system, reduces the requirements for the system's braking capacity, avoids damage to the wing structure, and enables precise adjustment and fault detection of wing motion.

Abstract

本发明公开了一种高升力系统位置控制方法,包括:由安装于高升力系统中的位置传感器读取翼面初始角度,由襟缝翼操纵手柄给定翼面目标运动卡位时的目标角度,从而得到翼面运动角度差;通过传动轴行程与翼面角度比值和微调量得到传动轴行程;利用加速阶段时间和减速阶段时间,并设定传动轴匀速阶段转速可得出加速阶段行程和减速阶段;基于总行程、加速阶段和减速阶段的行程、匀速阶段的转速与运动时间,得到匀速阶段行程,进而得到出传动轴匀速阶段转速;基于传动轴匀速阶段转速计算出加速阶段行程和减速阶段行程,最终确定传动轴实时转速与实时角度差的函数关系,根据函数关系进行高升力系统的位置控制。
