Hello every body !

  Wishing I am not annoying and borring you with my demands, I would like to ask
you if you have some references (articles, books, presentations) concerning
feedforward loops, used in advanced process control ? I lost a lot of time
seeking for such  documents and I didn't find anything !

  I need your help ! Thanks in advance and I am sorry for persons not concerned
!

  Best regards. Nader
