Regularization and passivity-preserving model reduction of quasilinear magneto-quasistatic coupled problems
Johanna Kerler-Back, Timo Reis, Tatjana Stykel
We consider the quasilinear magneto-quasistatic field equations that arise in the simulation of low-frequency electromagnetic devices coupled to electrical circuits. Spatial discre…
Balanced truncation for parametric linear systems using interpolation of Gramians: a comparison of algebraic and geometric approaches
Nguyen Thanh Son, Pierre-Yves Gousenbourger, Estelle Massart +1
When balanced truncation is used for model order reduction, one has to solve a pair of Lyapunov equations for two Gramians and uses them to construct a reduced-order model. Althoug…
Balanced truncation model reduction for 3D linear magneto-quasistatic field problems
Johanna Kerler-Back, Tatjana Stykel
We consider linear magneto-quasistatic field equations which arise in simulation of low-frequency electromagnetic devices coupled to electrical circuits. A finite element discretiz…
