For some papers off the net, try http://researchindex.com

For over 150 references and a good review paper try
"Fuzzy Logic in Control Systems: Fuzzy Logic Controller - Parts I & II",
C.C. Lee, IEEE Trans. Sys, Man & Cyb., SMC-20, pp. 404-435 (1990).

For a good general FLS book,
"Fuzzy Systems Theory and Its Applications", T. Terano, K. Asai and M.
Sugeno, Academic Press (1992).

For the earliest collection of FLC applications see
"Industrial Applications of Fuzzy Control", M. Sugeno, North-Holland (1985).

Together these should give you enough material.

A reasonably simple experiment is the water bath level control ...
a level sensor, a bucket, and the usual interfacing a/d instrumentation. It
also happens to be nonlinear because of the outflow orifice equation where
F_out = K * Level ^ 0.5. There can be a lot of noise in the sensors, so it's
deceptively nontrivial ... and not too expensive.

Good luck with your project and experimentation.
