Abstract :
The paper presents a new approach to the problem of automatic order reducing of a rational transfer function (TF). The approach is directed to obtain low-order models under criterion of minimal integral square error. The developed computational scheme allows one to determine the reduced model of the minimal order with a given error tolerance
