摘要
对于具有线性—限幅特性的非线性系统,在线性和非线性部分之间的任何信息都不知道的情况下,利用频谱分折的方法,可以得到线性和非线性部分的全部参数,并对限幅特性进行确认性检验。本文给出了识别全部参数的详细方法和步骤,最后给出了识别例题。
For the nonlinear system with a limiter at its output, the parameters of its linear and non-linear sections can be got by means of spectrum analysis method though the relationship between them is unknown. The paper deals with the identification of the system parameters with an example illustrated.
