In this paper, we propose a model order reduction method for a class of high-dimensional cascade system and it is derived by making use of the fact that the input-output properties of the system approach that of a diffusion system, described by partial differential equations, at a certain continuum limit. Reduced systems preserve the diffusional structure and the stability of the original system. In addition, the upper bound of the error caused by the order reduction is derived.
