N2 - Aiming at the necessity of aircraft gust load alleviation control and fast response requirements, a design method of gust load alleviation control law based on L1 adaptive control is proposed. First, an aircraft-gust comprehensive dynamics model is established. Based on the gust response characteristics of the uncontrolled aircraft, the dynamic response of the target aircraft under gust disturbance is analyzed, and the corresponding L1 adaptive control architecture is constructed. Afterwards, the L1 adaptive control algorithm is used to design the gust load alleviation control system of the target aircraft, including a state observer, a low-pass filter and an adaptive law. Finally, the wing root bending moment and wing tip overload are used as control parameters, and the control system is simulated and evaluated under the influence of continuous gusts and random gusts. The results show that the control system can make the gust load alleviation rate of the flexible aircraft reach more than 15%.
