نبذة مختصرة : In this paper, we extend the structure-preserving interpolatory model reduction framework, originally developed for linear systems, to structured bilinear control systems. Specifically, we give explicit construction formulae for the model reduction bases to satisfy different types of interpolation conditions. First, we establish the analysis for transfer function interpolation for single-input single-output structured bilinear systems. Then, we extend these results to the case of multi-input multi-output structured bilinear systems by matrix interpolation. The effectiveness of our structure-preserving approach is illustrated by means of various numerical examples. ; German Research Foundation (DFG)German Research Foundation (DFG) [2297, 1897]; National Science FoundationNational Science Foundation (NSF) [DMS-1439786, DMS-1720257, DMS-1819110]; Simons Foundation [50736]; Projekt DEAL ; Published version ; Open Access funding enabled and organized by Projekt DEAL.
