A Multiple Mode Armax Model of Nonlinear Systems--A Kind of Model Based on Interpolation Theory
非线性系统的多模态ARMAX模型——一种基于插值理论的模型

In this paper, based on the interpolation theory,a multiple mode moedl of nonlinear systems is developed. The MM models under non-equilibrium and equilirium are considered. Both of them are much more accurate than the traditional linearized model of nonlinear systems at one operating point.Especially the MM model under equilibrium is convenient to be identified and applied.The simulation results have shown the effectiveness of the MM model developed in this paper.
