Abstract

Active control research was carried out on the flutter of large wind power blades, and the flutter control and widening model of two-degree-of-freedom blades was established by using flexible tail flaps and NACA0012 airfoil as the research object. The Laguerre function is introduced to index correct the weight update strategy in the model predictive control （MPC） algorithm, and on this basis, the hierarchical structure idea is used to divide the blade vibration damping system into different control levels, and an adaptive combination control strategy with the vibration minimization as the control goal is designed. The simulation platform is used to analyze the control results of the proposed control strategy under standard working conditions and interference conditions, and the results show that the proposed method can effectively suppress the blade vibration under the coupling action of air-elasticity, reduce the vibration suppression energy consumption, and have better anti-interference performance compared with the conventional adaptive control method, which can further improve the adaptability of the wind power blade vibration control system in complex operating environments.
