You may read a recent paper "A neural-fuzzy sliding mode observer for robust fault diagnosis" (2009) by Qing Wu and Mehrdad Saif (ACC-2009 Proceedings) published by IEEE Press (ISBN: 978-1-4244-4523-3). See web-link : http://dl.acm.org/citation.cfm?id=1703152 (for abstract of this paper)
You may also read the paper by Qing Wu & Mehrdad Saif titled,
"Robust fault diagnosis of a satellite system using a learning strategy and second order sliding mode observer" (2010) in IEEE Systems Journal, Vol. 4, pp. 112-121.
You can find many paper, books or thesis related to SMC, I think you should to find a thesis which one of the best one is " fuzzy model-based adaptive robust control design and application to robot manipulators" by " Meysar Zainali", you also can to follow my papers I have more than 80 papers related to SMC with application to robot manipulator, continuum robot, IC engine and 3-D motor.
thank you for your answer and your time. it is very important for me that you answer to me. that paper was opened for me new science about fuzzy model and their application. please allow me to read that source (more and more). i try to use another your source. thank you
