摘要: 本文对颤振主动抑制控制律进行了研究。研究对象为一小展弦比带外侧导弹的机翼颤振模型,模型具有外侧后缘控制面。依据该模型的全部动力特性和刚度特性,以最优控制为基础,采用动态补偿器方法,设计了两阶控制律。对该控制律进行了风洞实验验证。实验结果表明:颤振临界速度提高了14%以上。理论计算结果与实验结果一致。

Abstract: The control laws of active flutter suppresion system for a low aspect ratio wing flutter model with outboard missile are studied. The model is equipped with an outboard trailing-edge control surface. Firstly, according to all dynamic characteristics and rigid characteristics of the model, a second order control law is designed using a dynamic compensator method based on the optimum control. Further, the control law is tested by the simulator during a wind-tunnel test. The experimental results indicate that the flutter critical speed increases by more than 14 percent. The calculated results are in good agreement with the experimental ones.
