I recently attended a Fuzzy seminar at the Omron facility in Sch.  They had
two demos of what they claim is the only "true" fuzzy controller.

One demo was the pendulum.  The feedback for the balanced stick came from a
reostat on the pivot point and balance compensation came from circular
motion of the base.  Several golf balls could be balanced on a dish!.

The second demo was temperature control.  This was more interesting in that
the fuzzy solution to PID was only used to maintain or recover temperature
fluctuations, but not to reach the initial temperature.  I pressed the
demonstrator, but he never gave me a satisfactory answer as to why fuzzy
was not used for the whole cycle.  Except to say that it did not work.

Both demo's used existing commercial hardware, with some modifications for
the pendulum.  The temp controller is available and Omron has a fuzzy logic
module available for their large scale PLCs, 1024 I/O.
