Based on the modern control theory, an aerofoil finite element control model is established by using MSC Nastran DMAP (Direct Matrix Abstraction Program). The vibration control is studied with linear quadratic optimal control theory proposed.

• 利用MSCNastran开发语言DMAP(DirectMatrixAbstractionProgram)；基于现代控制理论；建立机翼有限元结构的振动控制模型；并使用线性二次型最优控制理论对机翼结构进行振动抑制研究.
