摘要：

This comment explains why the passivity preserving frequency weighted model reduction technique of Heydari and Pedram is guaranteed to yield neither passive nor stable models in the case of double-sided weighting. It is further shown for this method that the passivity can be preserved in the single-sided weighting case only. An example is presented to show that their method may yield non-passive models for passive original systems in the case of double-sided weighting.
