Many classes of non-linear systems can be represented by Volterra kernels. In order to obtain the Volterra kernels, one of the authors has proposed a new method by use of M-sequences and correlation function.In this paper, the authors propose a new method for polynomial approximation of non-linear system using the Volterra kernels measured by the M-sequence method. The non-linear system can be approximated as a combination of a linear system and its squared portion. The parameters, which represent the relative magnitude of the squared part, is calculated by use of the Volterra kernels.The proposed method is applied to a non-linear chemical process. From the results of simulations, it is shown that the output signals of the non-linear system calculated by the proposed method agree well with the theoretical outputs.
