| 摘 要： | 在考虑机翼几何非线性的基础上,先在机翼平衡位置求出振动模态,然后构建机翼的广义受控对象式,设计出模型预测控制器,进行阵风响应减缓控制仿真,并与阵风响应进行对比。结果表明,模型预测控制器能有效地抑制阵风响应。

| Abstract: | Current, flutter suppression and gust load active control technology had been the hot topics in the study of aeroservoelasticity. In this paper, a new aeroelasticity method based on the MDO platform ISIGHT integrated Matlab and Nastran is developed for a high aspect ratio wing. First, normal models are computed at the static aeroelasticity balance position of the wing. Then a aeroservoelasticity closed-loop system of the wing is deceloped for the model-predictive gust load alleviation controller. Further, the gust alleviation performance is evaluated for the discrete gust. |
