摘要
本文提出了一种用函数束辨识弱非线性系统二阶Volterra核的方法——“函数束法”。此方法仅需考虑系统的输入和输出。其辨识过程实际由两个部分组成,即系统的线性响应辨识和系统的二阶响应辨识。
In this paper, the author Proposes an identification method for the second orderVolterra-kernel of weakly nonlinear systems by use of Pencil of Function. This method re- quires only that input and output terminal of the nonlinear systems be measured. The identifi-cation procedure is actually divided into two major parts i. e. the linear response of the systemand the second order response of the system.
