Dear Shann and Francis,
I am glad you discuss definitions of control and regulation because these
terms remain very confusing to me. First I would prefer to avoid the word
"goal" in the definition of control. I agree with Shann that control can exist
without a goal (unless we stretch the meaning of a goal beyond its limits).
I view control as an ability of an agent to change its behavior. Neither
deterministic nor stochastic systems are agents because they have no
control of their behavior. Watt's regulator is not an agent, and it has no
control of its behavior. The pressure in the tank is regulated but there is
no control here. It is an engineer who has control of Watt's regulator, and
he has a goal of maintaining the pressure.
A goal is a preferred state of the system. But societies and biological
populations have no preferred state. Nevertheless they can improve their
performance (adaptation and adaptability) without setting goals.

Traditional cybernetics is most successful in its application to man-made
mechanisms. Biological and social systems require a more sophisticated
method which Francis calls "second-order cybernetics". But the term "goal"
and comes from the first-order cybernetics; thus I am not
comfortable with it. On page 13 Francis mentioned evolutionary systems
that attempt to maximize their fitness or reproductive value. I think that
these terms are more relevant for "2-order cybernetics".
I am a biologist and I am interested in the area that is known as biosemiotics
(see my web page http://www.ento.vt.edu/~sharov/biosem/welcome.html ).
I wrote a paper on the differences between cybernetics (1st order) and
semiotics (which is very close to what Francis calls 2nd order cybernetics)
