本文系统地对非线性系统辨识算法及相关课题作了综述。包括 wiener和 Volterra 泛函展开,适合于框图的系统和双线性系统、输入信号的选择、结构检验,参数估计以及灾变理论的成果。对这些方法的局限性、相互关系以及可应用性均作了讨论。 This paper systematically reviews the nonlinear system identification algorithms and related topics. Including wiener and Volterra functional expansion, suitable for block diagram systems and bilinear systems, input signal selection, structural verification, parameter estimation and catastrophe theory. The limitations, interrelations, and applicability of these methods are all discussed.
