A Strejc model-based, semi-fractional (SSF) transfer function model

Abstract

In paper the proposition of Strejc model based, transfer func-
tion, fractional model, (called SSF model) is presented. The model
is dedicated to describe high-order control plants. Parameters of the
model were calculated numerically with the use of the least square
method and MATLAB/SIMULINK. Results of simulations show,
that the proposed model assures very good accuracy associated to
relatively low order in comparison to other models describing the
considered exemplary control plant.
