采用非迭代辨识算法研究非线性气动弹性系统特征。从系统的输入输出测量数据{uk,yk}kN=1中,用Ham-merstein Block-Oriented模型进行辨识。Block-Oriented模型辨识的重点是用一组与所研究系统动力学一致的先验正交基函数,本文采用气动弹性系统先验的极点信息构造正交基函数。最后,用二元机翼算例验证辨识方法的准确性。 Non - iterative Identification Algorithm for Nonlinear Aerodynamic Elastic System. From the system's input and output measurement data {uk, yk} kN = 1, it is identified by Ham-merstein Block-Oriented model. The emphasis of Block-Oriented model identification is to use a set of a-priori orthogonal basis functions consistent with the studied system dynamics. In this paper, we construct the orthogonal basis function using the prior pole information of the aeroelastic system. Finally, the binary wing example is used to verify the accuracy of the identification method.
