Abstract
Several methods have been developed to identify a parametric model thatrepresents the radiation force convolution term in Cummins’ equation.The reason behind such an approximation is twofold: obtaining a modelwith less computational (effort) requirements, and easing model-basedcontrol design procedures. In this paper, a case study on the paramet-ric approximation of such a convolution term using frequency-domaindata is considered, based on recent advances in model order reductionby moment-matching. Both the force-to-motion and radiation impulseresponse dynamics are considered. The advantages of a moment-basedstrategy are discussed, while providing a comparison with well-knownexisting methods.
