Abstract

In balanced truncation and Hankel norm reduction, any instabilities if present can only be treated by copying them into the reduced order object, which differs from the original object only through reduction of the stable part. This conclusion applies to frequency weighted reduction also, and thus to the controller reduction methods we have examined.
