Dear ARUN K. TANGIRALA,
>In your book, page 453, it says that the balanced truncation of a
>balanced realization model preserves the steady-state gain.
This is a MISPRINT, is should say that balanced residualization
preserves the steady-state gain.
>On page 467, in your book, second paragraph under Conclusions, it says
>that under several conditions, residualization is easier and preferable
>over Hankel Norm reduction/truncation.
Yes, but we NOT always recommend residualization over Hankel Norm
reduction/truncation.
Best regards,
Sigurd Skogestad
