| Abstract: | 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. With the powerful solution for large sparse matrix of MSC Nastran, the application of linear quadratic optimal control with negative feedback to the aerofoil is implemented and the good control effect is achieved. |
