| 摘 要： | 将小波理论应用于非线性系统的参数的识别中.首先将系统的微分方程投影到由Daubechies尺度函数张成的子空间中去,然后利用Daubechies小波的性质将系统微分方程转变为由未知参数构成的一个超越代数方程组,从而最终将系统参数识别问题转变为代数方程组的求解问题.

| Abstract: | A method of parameter identification of nonlinear systems based on Daubechies wavelet is presented.First the governing differential equation associated with the nonlinear model was projected on a subspace spanned by a finite number of Daubechies wavelets,the resulting algebraic equations are then rewritten with the parameters of the system as unknowns.Finally the problem of the parameters identification was converted into getting the resolutions of the algebraic equations. |
