"Intelligent control" sounds like another sales phrase, as in Foxboro IA.
Please explain exactly what you are talking about. The term does not have a
standard meaning.

Intelligent control is a vague term, which is very hard to define.
Therefore, it is hard to judge a controller if it is intelligent or
not. The hardness comes from the word "intelligent" itself, till now
there is no specific definition for that word.
Anyway, the logical definition of the word "intelligent" is not the
question here, but I aimed to notify the vagueness of any combination
of words contain this word.
Now, if we merge the control to the intelligent we have the question
what is the intelligent controller?
I guess, when people discovered the feed back control for the first
time, it was a very intelligent controller in this era, which is very
normal in ours.
In my own point of view, the controller will be intelligent if the
control task itself is an intelligent task.
It is not necessary to have one of the AI techniques within the
controller to change the controller to an intelligent one. In other
words, some of the traditional control (i.e. PID algorithms) is still
working very well and it is really a strong competitor to what people
called intelligent controllers.
The reason simply, because the control tasks assigned to the
intelligent controller is not intelligent tasks.
Using Fuzzy Logic, Neural Networks, Genetic Algorithms, predictive
methods, statistical analyses, etc…does not imply that your controller
becomes an intelligent one unless you have an intelligent task.
In my own point of view, a controller that, stands alone (without
human interaction) and performs a task very hard to achieved by
traditional controllers, is an intelligent controller, whatever the
techniques it uses.
The above lines do not deny that, some of the applications are working
amazingly with one or more of the new (Fuzzy Logic, Genetic or Neural
Networks) controllers but that is because of the nature of the control
task itself which is hard to be implemented by traditional
controllers.
if you like to get more about the intelligent controllers, refer to
the application of the fuzzy control and the remaining AI techniques
used in the control algorithms.
I think the best of Fuzzy Control application site is
http://www.aptronix.com /
The site is full of tasks based on Fuzzy Logic and working very well.

I wish I had 10 cents for every young person I meet who wants to know
more about fuzzy/neural/genetic/adaptive or whatever type of control,
when they have never even heard of classical frequency domain loop
shaping, nor done more than a couple of contrived pen and paper
tutorial designs. What are university academics teaching!? No wonder I
hear comments about things like
digital anti-aliasing filters. The mind boggles!
