Abstract

A study the accuracy and noise immunity of a method of deterministic identification of nonlinear dynamic systems in the form of Volterra kernels based on the differentiation of the feedback parameter is the amplitude of the test signals. The calculation of derivatives is reduced to the solution of the corresponding linear integral Volterra equation of the first kind. The computational stability of the method of identification is provided by using the method of regularization of ill-posed problems A.N. Tikhonov. To smooth the estimates of the Volterra kernels used wavelet filtering.Tabl: 1.
