A new method for the model reduction technique via a limited frequency interval impulse response Gramian

Abstract

A newly proposed method of frequency-weighted model reduction for single-input–single-output (SISO) linear continuous-time systems is proposed. It is based on matching the elements of the limited frequency interval impulse response Gramian (IRG). A numerical example is given to illustrate the method, which is then compared with other well-known model reduction methods.
