研究了具有波纹结构的变形控制面的气动伺服弹性特性。采用有限元结构模型和非定常涡点阵法气动模型分析了波纹变形控制面的气动弹性响应。以状态空间形式推导了波纹变形控制面的运动方程，并结合经典的LQR控制技术将变形结构作为控制面。考虑结构和控制设计参数，分析了波纹变形控制面在连续阵风作用下的气动伺服弹性响应。仿真结果表明，即使采用驱动控制，波纹的柔性设计也可能导致不良的振动。研究还表明，在升力控制中起重要作用的结构模态可以根据结构设计参数而变化。这项工作为设计具有柔性结构（如波纹结构）的变形控制面提供了重要的见解。
Aeroservoelastic characteristics of a morphing control surface with corrugated structures are investigated in this paper. The finite element structural model and the aerodynamic model with an unsteady vortex lattice method are used to analyze the aeroelastic response of a corrugated morphing control surface. The equation of motion for the corrugated morphing control surface is derived in the state-space form, and a classic LQR control technique is integrated to function the morphing structures as control surfaces. Considering the structural and control design parameters, the aeroservoelastic response of corrugated morphing control surfaces under continuous gusts is analyzed. Simulation results demonstrate that the flexible design of corrugations may lead to undesirable vibrations even with actuation control. It is also shown that the structural modes which play important roles in the lift control can change according to the structural design parameters. This work provides important insights into designing a morphing control surface with flexible structures such as corrugated structures.
