Interpolation strategy for BT-based parametric MOR of gas pipeline-networks
- Proceeding from balanced truncation-based parametric reduced order
models (BT-pROM) a matrix interpolation strategy is presented that allows the
cheap evaluation of reduced order models at new parameter sets. The method ex-
tends the framework of model order reduction (MOR) for high-order parameter-
dependent linear time invariant systems in descriptor form by Geuss (2013) by
treating not only permutations and rotations but also distortions of reduced order
basis vectors. The applicability of the interpolation strategy and different variants is
shown on BT-pROMs for gas transport in pipeline-networks
