摘要
对于典型的Hammerstein模型,如“死区一线性”和“空回一线性”系统模型,在非线性和线性部分之间的任何信息都不知道的情况下,只根据系统输入和输出信息,利用频谱分析方法,可以识别出非线性和线性部分的全部参数,并对非线性特性进行确认性检验。本文给出了识别系统全部参数的方法和步骤,最后以例题说明。
For the typical Hammerstein model, for example, “ dead space-linear” and “ backlash-linear” nonlinear systems, when no information between nonlinear and linear parts is known, the parameters of its nonlinear and linear parts can be got by means of spectrum analysis method, and conformity of the nonlinear parameter can be verified. The method and steps for identification of the system parameters are introduced in the paper.
