应用最优控制理论和Ｌａｇｒａｎｇｅ插值建立了任意回转面三元叶片的平面叶栅优化设计的数学模型。用小波理论求解此模型得到一批数值结果。结果分析表明小波方法较传统方法更加有效。
The optimal control theory and Lagrange interpolation are used to establish the mathematical model of the plane cascade optimization design of any revolving plane ternary blade. Using wavelet theory to solve this model, we get a series of numerical results. The result shows that the wavelet method is more effective than the traditional method.
