ABSTRACT
This note presents a study of the effect of time-moments and Markov-parameters on reduced order modeling and to identify suitable combination of time-moments and Markov-parameters to highlight the significance of retaining or near retaining a few terms (time-moments/Markov-parameters) in excess of r terms in arriving at a good overall time response approximation, where r denotes the order of the reduced-order model. To identify appropriate combination of time-moments and Markov-parameters of the system to be retained in the reduced-order model for obtaining good overall time response approximation, system under consideration are of nature: Critically-damped system, under-damped system with small settling time and under-damped system with large settling time.
