In this paper an alternative version of existence condition of discrete-time normal form is derived for MIMO nonlinear systems. The proposed condition for non-singular discrete-time systems is formulated in a compact form. The theoretical results of the new condition are further investigated through examples. © 2006 Elsevier B.V. All rights reserved.
