Abstract :
In this paper two extensions to an optimization based model reduction method are considered: frequency-weighted and parameter-dependent model reduction. The performed extensions are simple and natural, this fact illustrates the advantages of the method. Also, the methods may be applied using an exact model or frequency samples of a model. We construct numerical examples to illustrate both extensions.
