Hello Zahid, Your questions below are on *State Estimation*, which is probably off-topic for the this mailing list. May I suggest that you direct this type of questions to a forum such as Eng-Tips, for instance ( http://www.eng-tips.com/threadminder.cfm?pid=238). Maybe others in the mailing list can suggest other better forums.
Two good references on State Estimation are: * http://www.springer.com/engineering/electronics/book/978-0-7923-8519-6 * http://www.crcpress.com/product/isbn/9780824755706 See also http://www.eng-tips.com/faqs.cfm?fid=1287 Hope it helps, -- Jose L.
