    Abstract

    This report deals with the concept of equivalent dead time13; and its use in the simplification of s-domain and z-domain higher order transfer functions (HOTF).A preliminary lower order transfer function (LOTF) is obtained by retaining a few dominant poles and zeros of the HOTF.This lower order model is then enhanced by including a pure time delay element. This element is related to the difference between13; equivalent dead times of HOTF and the preliminary LOTF. FORTRAN routines are developed for this procedure and several examples are given to illustrate the procedure.
