For monovariable systems, if the nominal transfer function is irreducible the minimal order is tlw clqwr of'tllr(/~~tl(~l~litl~ltot.~)ol!'l~ol~liCtl. In multivariable systems. this order is (I/ krst equal to the degree of the last common multiple of the denominators of the transfer matrix function e
## This paper considers the problem of optimally approximating high-order transfer functions by low-order ones with a time delay. The performance index used for optimization is the integral of squared error (BE) between the unit-step responses of the reduced-order and original transfer functions.
