On the Connection Between Gramian-based and Interpolation-based Model
Order Reduction
Gramian-based model order reduction methods, like balanced truncation, and interpolation-based methods, such as H2-optimal reduction, are two important types of model reduction algorithms. Although both are known for their accuracy, they are often seen as two different approaches. This paper shows that these two methods are closely related, with Gramian-based …
