✦ Synopsis

A new methodfor the model reduction of linear discrete stable systems in Z-transfer functions is presented. First, a set of parameters is defined, whose values uniquely determine the given system. Then an always stable reduced approximant is obtained by neglecting the parameters which do not contribute signijcantly in theformation of the system's responses. The proposed method slightly modijed also preserves, in the reduced model, the rank of the given system. Formulae are provided to select the reduced order.

Nonlinear nondynamic systems which can be modelled by a linear combination of nonlinear functions are considered. An algorithm, based on correlation techniques, is presented for reducing the number of terms in such a model to a fixed but arbitrary number, n. It is shown that when the model is a line
