Poincare-Steklov filter in hardware-in-the-loop modeling
Power hardware-in-the-loop modeling (PHIL) is one of advanced approach for test automation and verification of complex circuits and systems. This approach is most well used in power networks and power-trains. PHIL modeling is supposed part of a system is software model whether the other part is hardware item under test. A special interface algorithm supports interaction between computer model and device under test. This algorithm has to provide stability of decomposed system and numerical convergence of the simulation results. This paper is discussed damping impedance method (DIM) and introduced new interface algorithm named generalized coupling scheme (GCS), which allows to implement interaction procedure between software and hardware parts in a simpler way. Moreover, we introduce Poincare-Steklov filter, which can be considered as hardware implementation of GCS.
