Preserving transfer-behavior in Model Order Reduction for thermoacoustic stability analysis
N Purwar, W Polifke - Journal of Sound and Vibration, 2023 - Elsevier
Thermoacoustic systems are often modeled with a hybrid approach that combines separate
models for acoustic propagation and flame dynamics. Model Order Reduction (MOR) may …

Relative error-based time-limited H2 model order reduction via oblique projection
In time-limited model order reduction, a reduced-order approximation of the original high-
order model is obtained that accurately approximates the original model within the desired …
