摘　　要：阐述了基于弦向襟翼的风力机翼型建模及振动控制。结构模型是基于一种准2D翼型的实验平台,平台包括阻尼-弹簧减振器、弹簧限位器及弦向襟翼结构。基于干扰观察器的滑模控制算法,研究了基于襟翼摆角的振动控制方法。MATLAB仿真结果不仅展示了控制方法的有效性,也展示了襟翼摆角输入在实验平台实现的可行性。This study is to investigate airfoil modelling and vibration control of wind turbine based on chordwise flap.The structural model is based on a quasi-2D airfoil experimental platform that includes a damping-spring damper,a spring retainer,and a chord-like flap structure.Based on the sliding mode control algorithm of the disturbance observer,the vibration control method based on the flap angle is studied.The MATLAB simulation results not only demonstrate the effectiveness of the control method,but also demonstrate the feasibility of the flap angle input in the experimental platform.
