Parametrische Modellordnungsreduktion

The main goal of parametric model order reduction of linear systems is to find a reduced model that preserves the parameter-dependency, thus allowing a variation of any of the parameters without the need to repeat the reduction step. Thereby, the reduction method should ideally be able to cope with a high number of parameters and with systems where no analytical expression of the parameter-dependency (should not be limited to being linear) in the matrices is available. In addition, it should be numerically efficient to be suitable for the reduction of large-scale systems and at the same time its computational cost should be low enough to keep the reduction step numerically justified.

The parametric model order reduction algorithms developed at MORLab are included in our psssMOR toolbox, which is free and available for download.
